| Abstract: This manuscript discusses a new design of large area MCP-PMT for the next generation neutrino experiments. The main motivation of the design is to improve the quantum efficiency (photo detection efficiency) of the PMT. Two sets of small MCP units, the transmission photocathode coated on the front hemisphere and the reflection photocathode coated on the rear hemisphere are assembled in the same glass envelope to form nearly 4 pi viewing angle to enhance the efficiency of the photoelectron detection. The photoelectrons from the 4 pi photocathode are collected and amplified by two sets of MCP units. Our goal is eventually to produce 20 in. diameter PMT following such an approach. We will report preliminary results of our ptoelectronic simulation and the results of a 5 in. diameter prototype PMT. Future plans and prospects are discussed at the end. (C) 2011 Elsevier B.V.

| Abstract: The characteristics of laser-induced periodic surface structures (LIPSS) were investigated after laser irradiation with different pulse duration under a certain range of laser fluence (0.25 <= Phi <= 1.91 J/cm(2)) and pulse number (11 <= N <= 560). Spikes were generated by picosecond laser irradiation in ambient air, in comparison with only periodic ripple structures introduced by nanosecond and femtosecond laser irradiation. Microstructural investigations indicate that these spikes were initiated by the fragment of periodic ripple ridges or corrugation on the smooth surface with subsequent pulses, and their separation increased with increasing the laser fluence. Surface capillary waves associated with the resolidification process can be employed to explain the formation of spikes by picosecond laser irradiation. (c) 2012 Elsevier B.V. All rights reserved. |

| Abstract: X-ray phase-contrast imaging based on grating interferometry is a technique with the potential to provide absorption, differential phase contrast, and dark-field signals simultaneously. The multi-line X-ray source used recently in grating interferometry has the advantage of high-energy X-rays for imaging of thick samples for most clinical and industrial investigations. However, it has a drawback of limited field of view (FOV), because of the axial extension of the X-ray emission area. In this paper, we analyze the effects of axial extension of the multi-line X-ray source on the FOV and its improvement in terms of Fresnel diffraction theory. Computer simulation results show that the FOV limitation can be overcome by use of an alternative X-ray tube with a specially designed multi-step anode. The FOV of this newly designed X-ray source can be approximately four times larger than that of the multi-line X-ray source in the same emission area. This might be beneficial for the applications of X-ray phase contrast imaging in materials science, biology, medicine, and industry. |

| Abstract: In the paper, a neural control scheme is presented for an UAV automatic landing problem under the failure of stuck control surfaces and severe winds. The scheme incorporates a neural controller which augments an existing conventional controller called Baseline Trajectory Following Controller (BTFC). The neural controller is designed using Single Hidden Layer Feedforward Networks (SLFNs) with additive or Radial Basis Function (RBF) hidden nodes in a unified framework. The SLFNs are trained based on the recently proposed neural algorithm named Online Sequential Extreme Learning Machine (OS-ELM). In OS-ELM, the parameters of hidden nodes (the input weights and biases of additive nodes or the centers and impact factors of RBF nodes) are randomly selected and the output weights are analytically determined based on the sequentially arriving data. Performance of the proposed neural control scheme is evaluated on a typical aircraft autolanding with a single stuck failure of left elevator. The simulation results demonstrate good fault tolerant performance of the proposed neural fault tolerant controller. |

| Abstract: The panoramic image has been widely used in social production, and has become an important topic in research on the field of image processing. For complex images with multiple scenes and other elements, the algorithm that is based on Harris cannot make image registration effectively. This paper proposes a method that combines Harris with SIFT, using the Harris algorithm with adaptive threshold to extract the corners and the SIFT descriptor to make the registration. It improved registration efficiency sub-effectively for the image in complex scenes, and generated a 360-degree panoramic image quickly. The experiments showed that the algorithm is adaptable and robust. | ||||||

| Abstract: Theoretical calculation indicates that the large exponential-doping GaAs photocathodes have a much narrower electron energy distribution than traditional GaAs NEA cathodes, and the excellent performance attributes to the special structure characters of the band-bending region and lower negative electron affinity of the new-type GaAs photocathodes. The effects of surface doping concentration and work function on the energy distribution are discussed in details, and the FWHM of the energy distribution is less than 100meV. The simulation results indicate that the large exponential-doping mode further improves the features of the electron energy spreads for GaAs photocathodes, which may meet the further demand of next generation of electron guns. | |||||||||

| Abstract: To solve the nonlinear filtering problem in the Bearings-Only Tracking (BOT), an improved particle filter with fine resampling is proposed, called as PF-FR (Particle Filter with Fine Resampling). By introducing distance-comparing process and generating new particle based on optimized combination scheme, PF-FR filter performs better than generic PF-SIR filter both in terms of effectiveness and diversity of the particle system, hence, evidently enhancing tracking accuracy in bearings-only tracking problem. Simulations indicate that the proposed PF-FR algorithm is effective. (C) 2011 Published by Elsevier Ltd.

| Abstract: Atlas selection plays an important role in multi-atlas based image segmentation. In atlas selection methods, manifold learning based techniques have recently emerged as very promisingly. However, due to the complexity of anatomical structures in raw images, it is difficult to get accurate atlas selection results by measuring only the distance between raw images on the manifolds. In this paper, we tackle this problem by proposing a label image constrained atlas selection (LICAS) method to exploit the shape and size information of the regions to be segmented from the label images. Constrained by the label images, a new manifold projection method is developed to help uncover the intrinsic similarity between the regions of interest across images. Compared with other existing methods, the experimental results of segmentation on 60 Magnetic Resonance (MR) images showed that the selected atlases are closer to the target structure and more accurate segmentation can be obtained by using the proposed method. | ||||||||||||||||||

| Abstract: Focusing properties of a new kind of plasmonic lenses are investigated in the visible wavelength range through a subwavelength metallic chirped slit arrays which have the same depth but chirped widths. The chirped widths of slits are like a piece-wise-linear distribution which will be approximated by linearly increasing the width of a subwavelength feature and can build up a required phase front for focusing. We analyzed the focusing characteristics of different metallic lenses (silver and gold, respectively) with chirped widths that are obtained by generalizing the relevant phase delay for TE- and TM-polarized incident waves, for different f-numbers of lenses and for different material thickness, respectively. Meanwhile, the comparison of the metallic and dielectric lenses is also presented. The results of calculations show that, the metallic lenses are more sensitive to the polarization of incidence wave than that of dielectric lenses, and can get narrower full-width half-maximum (FWHM) beam width than that of dielectric lenses for TM-polarized incident waves, respectively. No matter which f-number we choose, the FWHM of dielectric lenses are higher than the plasmonic lenses, and the plasmonic lenses can get a higher focal resolution than dielectric lenses do. This kind of plasmonic lenses should have a good potential for applications in photonic and plasmonic integrated devices, sensing, and nano-optical manipulations, etc. |

| Abstract: As one type of the deployable telescope, the deployable space telescope under researching uses tape springs as the support structure of secondary mirror. Before launch, the support structure of secondary mirror is folded, and when on orbit the structure is deployed. Usually the secondary mirror is not on the nominal position after deploying, so the alignment of the secondary mirror is needed. To achieve this we need to obtain the deployment errors. So the measuring of secondary mirror deployment errors of thus deployable telescope is an important topic. In this paper, we designed an accurate measuring system based on position sensitive detectors (PSDs) to measure the deployment errors, through measuring the six-degree-of-freedom motions of the secondary mirror. The measuring system contains 3 two-dimensional PSDs, 3 laser diodes and 3 small mirrors. In order to resolve the deployment errors, the equations linking the PSD readings and the six-degree-of-freedom displacement of the secondary mirror were deduced. These equations are solved through a numerical method. Finally, we did measuring experiments on a deployable prototype. The experimental results show that this deployable prototype has deployment errors about 100um. | ||||||

| Abstract: Image quality assessment (IQA) algorithms are important for image-processing systems. And structure information plays a significant role in the development of IQA metrics. In contrast to existing structure driven IQA algorithms that measure the structure information using the normalized image or gradient amplitudes, we present a new Local Structure Divergence (LSD) index based on the local structures contained in an image. In particular, we exploit the steering kernels to describe local structures. Afterward, we estimate the quality of a given image by calculating the symmetric Kullback-Leibler divergence (SKLD) between kernels of the reference image and the distorted image. Experimental results on the LIVE database II show that LSD performs consistently with the human perception with a high confidence, and outperforms representative structure driven IQA metrics across various distortions. | ||||||||||||||||||

| Abstract: The white balance is an important parameter of digital camera which makes a great impact on the application of digital cameras. However, due to the limitations of hardware of digital camera, the output image of digital camera cannot restore true colors of the objects under the different light sources conditions. And existing automatic white balance (AWB) algorithms have many application restrictions, particularly the single color image, the algorithms always failure to adjust. To solve this problem, this paper proposes an optimized algorithm based on the gray world assumption and HSI color model. According to the R, G and B color components probability distribution, the algorithm adjusts the image by using the difference value of color. Experimental results show that our algorithm can adjust images in complex situations; meanwhile these confirm that this method is not only effective, but also has the advantage of easy realization. |

| Abstract: Blind image quality assessment (BIQA) is an important yet difficult task in image processing related applications. Existing algorithms for universal BIQA learn a mapping from features of an image to the corresponding subjective quality or divide the image into different distortions before mapping. Although these algorithms are promising, they face the following problems: 1) they require a large number of samples (pairs of distorted image and its subjective quality) to train a robust mapping; 2) they are sensitive to different datasets; and 3) they have to be re-trained when new training samples are available. In this paper, we introduce a simple yet effective algorithm based upon the sparse representation of natural scene statistics (NSS) feature. It consists of three key steps: extracting NSS features in the wavelet domain, representing features via sparse coding, and weighting differential mean opinion scores by the sparse coding coefficients to obtain the final visual quality values. Thorough experiments on standard databases show that the proposed algorithm outperforms representative BIQA algorithms and some full-reference metrics. | |||||||||||||||||||||

| Abstract: Developing reduced reference image quality assessment (RRIQA) plays a vital role in dealing with the prediction of the visual quality of distorted images. However, most of existing methods fail to take color information into consideration, although the color distortion is significant for the increasing color images. To solve the aforementioned problem, this paper proposed a novel IQA method which focuses on the color distortion. In particular, we extract color features based on the model of color fractal structure. Then the color and structure features are mapped into visual quality using the support vector regression. Experimental results on the LIVE II database demonstrate that the proposed method has a good consistency with the human perception especially on images with color distortion. | ||||||||||||||||||

Firstly, a transistor should be suitably chosen, here we accomplish the direct current (DC) simulation in order to get the right quiescent operating point under the platform Advanced Design System 2009 (ADS). Then some stability simulations and measurements were taken to make sure that the amplifier can be unconditionally stable. Finally, we carried out the load pull and source pull simulations to obtain the load and source impedances required, while executing the Harmonic Balance (HB) simulations to verify our design. |

Moreover the effect of the thickness of the guiding section on the energy distribution in the far-field is analyzed. With proper parameters design, more than 99% of the annular light emitted from ACF could be centralized at a bright spot in the far-field. These results may provide a theoretical guidance for the design and application of ACF. |

| Abstract: In optical trapping, annular beam as a kind of hollow beam is used to increase the axial trapping efficiency as well as the trapping stability. In this paper, a method for producing an annular beam by a system consisting of a single axicon and a pair of lens is proposed. The generated beam was also used as the optical tweezers. We use the geometrical optics to describe the propagation of light in the system. The calculated intensity distribution in three-dimensional space after the system shows a good agreement with the experimental results. The advantages of this method are simplicity of operation, good stability, and high transmittance, having possible applications in fields like optical microscopic, optical manipulation and electronic acceleration, etc. | ||||||||||||

| Abstract: The interferometric fiber optic gyroscope (IFOG) is a nonlinear response system. The noise, which results from the optic and electrical parts of the gyro for the environmental disturbance, includes both nonlinear noise and additive noise, and degrades the bias stability of the gyro. In this paper, the nonlinear state equation about the closed-loop IFOG is deduced from analyzing the sources, characteristic and effect of noise, and then the scaled unscented Kalman filter (SUKF) with augmented state is presented to reduce the noise. The experiment showed that: by adjusting SUKF parameters, it evidently decreases the standard deviation and Allan variance of the bias stability. Therefore this algorithm achieves better performance of filtering and improves effectively the bias stability of the gyro. (C) 2011 Published by Elsevier Ltd.

| Abstract: We show that incoherently coupled multicomponent beam evolution equations in the low-amplitude regime in biased photorefractive-photovoltaic crystals can exhibit the analytical solutions of multicomponent solitons, which are due to both the spatially nonuniform screening of the external electric field and the photovoltaic effect. These multicomponent solitons can be obtained for N self-trapped mutually incoherent optical beams, where N is an arbitrary whole number. When the photovoltaic effect is neglected, their nonlinear evolution equations change into that for multicomponent screening solitons, and these multicomponent solitons change into multicomponent screening solitons. When the external bias field is absent, their nonlinear evolution equations change into that for multicomponent photovoltaic solitons in closed and open circuits, and these multicomponent solitons change into multicomponent photovoltaic solitons in closed and open circuits. | |||||||||

| Abstract: We demonstrate an all-fiber all-normal-dispersion Yb-doped fiber laser that is passively mode locked by a graphene oxide (GO)-polymer. Because of good solution processing characteristic of the GO to polymer, a GO-polymer saturable absorber (SA) was successfully fabricated. Self-started mode-locking laser performance was investigated comprehensively at different cavity lengths, from 5, 24, to 94 m. The results showed that the pulse duration varies from hundreds of picoseconds to nanoseconds. In addition, the average output power of the mode-locked fiber laser can reach up to 500 mW. Furthermore, it was demonstrated that pulses with large chirps can be more easily amplified to reach high output power. | |||||||||||||||

| Abstract: This paper presents a video stabilization algorithm based on Scale Invariant Feature Transform and the improved RANdom SAmple Consensus (RANSAC) algorithm. Feature points of the video images are extracted using the SIFT algorithm, and then a compensation matrix is obtained using the improved RANSAC algorithm. Pre-detection is used to accelerate the computation by discarding those temporary models that are not candidate models. The experiment result shows that this algorithm largely reduces the amount of computation, as well as improves the speed of video stabilization without changing the accuracy notably. | ||||||

| Abstract: As a central problem in computer vision and pattern recognition, data representation has attracted great attention in the past years. Non-negative matrix factorization (NMF) which is a useful data representation method makes great contribution on finding the latent structure of the data and leads to a parts-based representation by decomposing the data matrix into a few bases and encodings with non-negative constraints. However, non-negative constraint is insufficient for getting more robust data representation. In this paper, we propose a novel method, called A-Optimal Non-negative Projection (ANP) for image data representation and further analysis. ANP imposes a constraint on the encoding factor as a regularizer during matrix factorization. In this way, the learned data representation leads to a stable linear model no matter what kind of data label is selected for further processing. Thus, it can preserve more intrinsic characteristics of the data regardless of any specific labels. We demonstrate the effectiveness of this novel algorithm through a set of evaluations on real world applications. | |||||||||||||||

| Abstract: The electroexplosive devices(EED) are widely used in the core system of rocket, missile and nuclear weapons. Hazard analysis and measurement of electromagnetic pulse is of great importance to the security and reliability of EED.

The temperature of EED can be measured through the fluorescence lifetime, then the induced current is obtained, and thereby the electromagnetic pulse induced hazard can be draw. The experiments show that, the set-up of this proposal can works with high precision and fast response, and immune to the electromagnetic interference. | ||||||

| Abstract: The choice of the over-complete dictionary that sparsely represents data is of prime importance for sparse coding based image super-resolution. Sparse coding is a typical unsupervised learning method to generate an over-complete dictionary. However, most of the sparse coding methods for image super-resolution fail to simultaneously consider the geometrical structure of the dictionary and corresponding coefficients, which may result in noticeable super-resolution reconstruction artifacts. In this paper, a novel sparse coding method is proposed to preserve the geometrical structure of the dictionary and the sparse coefficients of the data. Moreover, the proposed method can preserve the incoherence of dictionary entries, which is critical for sparse representation. Inspired by the development on non-local self-similarity and manifold learning, the proposed sparse coding method can provide the sparse coefficients and learned dictionary from a new perspective, which have both reconstruction and discrimination properties to enhance the learning performance. Extensive experimental results on image super-resolution have demonstrated the effectiveness of the proposed method. | |||||||||||||||||||||||||||

| Abstract: Position and orientation control for an omnidirectional mobile robot are investigated. The table-placed robot shall be used for arm and shoulder rehabilitation of stroke patients. The position and orientation of the device are determined by means of a modified Kalman filter which encompasses a kinematic model of the robot. By fusing information from incremental encoders at the robot and from an infrared camera at the ceiling, accurate and reliable estimates of robot position and orientation can be obtained. A cascaded position controller is designed for the mobile robot to allow the tracking of arbitrary translational reference movements and the stabilisation of the robot orientation. On the inner control loop, individual angular velocity controllers have been implemented for the three wheels to achieve maximum actuator performance and to facilitate a simplified state-space description of the robot dynamics. For the outer loop, a multi-variable state-space controller is utilised in form of a discrete-time linear quadratic regulator. The sensor fusion scheme and control system are validated in experiments and the obtained results are discussed. | ||||||

| Abstract: this paper introduces a research on signal processing of a precision photoelectric angle measuring system, and some key issues of the problem are also discussed and analyzed in detail. The basic principle of this measuring method is introduced in this paper. In order to avoid low frequency noise (such as generation recombination noise and 1/f noise), we choose to modulate the light source so that we can analyze the useful information in a high frequency domain. By using the data acquisition system (based on DSP and FPGA) to gather multiplex data, we can realize data-transmitting with network in a high speed. Writing algorithm by LabVIEW software in the data processing, we can eventually gain the angle. Prototype test shows that this method can completely meet the system requirements for the measuring system. | |||||||||

| Abstract: In order to overcome the disadvantages of the traditional auto-focus algorithms which are poor in real-time performance, weak in anti-noise capability and vulnerable to the influence of contrast and background pixels, this paper proposes an auto-focus algorithm based on maximum gradient and threshold. It introduces a threshold factor and takes a new kind of adaptive threshold to remove the pixels contaminated by noise and background in the image, then uses improved Sobel operators to extract maximum gray gradient after image preprocessing and calculates evaluation value. The experimental results show that the proposed algorithm has good real-time performance, strong unimodality, high sensitivity and strong anti-noise capability. In addition, the algorithm is less influenced by contrast and background pixels of the image. It can also control the sensitivity and focusing range of the focusing function. So the proposed algorithm is most suitable for auto-focus subsystem of video monitoring and tracking system. | |||||||||

| Abstract: Determine the misalignment of optical element quickly and exactly is the key to the technology of computer-aided alignment (CAA). For alignment a three-mirror off-axis field bias system, the sensitivity matrix method was used to simulate the alignment process. The results of simulation show that the sensitivity matrix method was not convergence. A new CAA method to get misalignment was put forward; the misalignment was obtained by programming the function of optical design software CODE V's auto-optimization option. The system's alignment characteristic was analysis and made use of this new method put up a computer simulation. The results of simulation show that the misalignment determined by only once auto-optimization and guidable to alignment of this system. After alignment, the optical system produced a measured wave front error across the all image plane less than 0.08 waves RMS at lambda=0.6328 mu m. |

| Abstract: Scale invariant feature transform (SIFT) is a better corner extraction algorithm, but there are still mismatching problems in the feature matching step. A new matching principle based on vector similarity is proposed and then it is compared with traditional matching principle. Firstly, the matching feature points are detected by the new principle. Mismatching points are further removed by using the mutual mapping theory. Secondly, transformation matrix is calculated by random sample consensus (RANSAC). Furthermore, the matrix is optimized by Levenberg-Marquardt algorithm (L-M). Lastly, image mosaic is realized by image fusion. Experimental results indicate that compared with traditional matching principle, new matching principle has improved matching accuracy. It is able to apply new principle to image registration and image mosaic. | ||||||

| Abstract: Segmenting bladder wall for thickness measuring is a fundamental operation in bladder magnetic resonance (MR) image analysis since thickening of the bladder wall may indicate abnormality. Active contours have been used for bladder wall segmentation, which can be broadly divided into gradient-based and region-based methods, according to the used image features. However, the artifacts in MR images and the complex background outside the bladder lead to significant challenges for segmentation. In this paper, a coupled directional level set model is proposed to segment the outer and inner boundaries simultaneously by exploiting the directional gradient, region information and thickness prior of the bladder wall. With our proposed method, the influence of the artifacts in the bladder lumen and the complicated intensity distribution of soft tissues surrounding the bladder can be appreciably reduced. Promising results on 119 bladder MR images have demonstrated the performance of the presented method. | ||||||||||||||||||

| Abstract: Enhancing brain tumor segmentation for accurate tumor volume measurement is a challenging task due to the large variation of tumor appearance and shape, which makes it difficult to incorporate prior knowledge commonly used by other medical image segmentation tasks. In this paper, a novel idea of confidence surface is proposed to guide the segmentation of enhancing brain tumor using information across multi-parametric magnetic resonance imaging (MRI). Texture information along with the typical intensity information from pre-contrast T1 weighted (T1pre), post-contrast T1 weighted (T1post), T2 weighted (T2), and fluid attenuated inversion recovery (FLAIR) MRI images are used to train a discriminative classifier at pixel level. The classifier is used to generate a confidence surface, which gives a likelihood of each pixel being a tumor or non-tumor. The obtained confidence surface is then incorporated into two classical methods for segmentation guidance. The proposed approach was evaluated on 19 groups of MRI images with tumor and promising results have been demonstrated. | ||||||||||||

| Abstract: Phenomenon of slow light has long been a hot research topic due to its promising and potential applications in communication networks, signal processing, optical sensors and nonlinear interactions. Particularly, photonic crystal devices, being capable of supporting slow-light propagation, are much attractive owing to its room-temperature operation and tunable dispersion features. Among them, photonic crystal waveguides (PCWs) are specially used in compact devices, while photonic band-gap fibers (PBGFs) are usually used in short-distance propagation and high sensitive interferometers. In this paper, dispersion tailoring schemes for obtaining a high group index with the wide band and low group velocity dispersion (GVD) are reviewed in both PCWs and PBGFs. For the same purpose, we propose schemes for the slow-pulse propagation in PCWs based on the air-hole shifting method and in PBGFs based on the microfluid infiltration method, respectively. Simulation results using 2D plane wave expansion method and finite-difference time-domain (FDTD) method are given. Pulse distortion and design optimization are also discussed in some detail with the consideration of the practical fabrication errors. Slow-light pulse propagation in photonic crystal fiber is also demonstrated in the experiment based on stimulated Brillouin scattering. | ||||||||||||

| Abstract: Slow light plays an important role in the fields of all-optical signal processing and integration photonics. It has shown many potential applications, such as realizing optical delay lines or buffers, enhancing linear and nonlinear light-matter interactions, as well as increasing the sensitivity of the interferometers and transducers. In this paper, hollow-core photonic bandgap fibers made from high index glasses are designed by infiltrating microfluid into the air-holes to tailor the fiber dispersion for slow-light propagation under low pulse distortion. In such a fiber made from Si material, group index n(g)similar to 8 is obtained with a bandwidth up to 30 nm, where the group index fluctuation is restricted in +/- 10 % of the n(g), while n(g)similar to 6 is obtained with a bandwidth over 100 nm when the chalcogenide material is selected instead. Such a +/- 10 % criterion determines a regarded flatland region accordingly, and in this region the group velocity dispersion can be negligible. It is found that for the same fiber length the slow-light time delay in the photonic bandgap fiber is much larger as compared with that in the single mode fiber. This kind of photonic bandgap fiber may have many potential applications in short-distance fiber communications and delay lines. | ||||||

| Abstract: We present a theoretical model to study the static pressure distribution among the layers of an optical fiber cable spool based on the force analysis of the cable system. Using the distributed fiber Bragg grating (FBG) sensing technique, the static pressures within the fiber cable layers of the spool were measured according to the Bragg wavelength shifts of the FBGs embedded in the cable. The effects of the cable spool shrinkage owing to the pressure from outer fiber cable layers on the cable tension and the radial pressure were analyzed in detail. As a result, the relationship between the applied static pressure upon the fiber and the resulted Bragg wavelength shift of the FBG was deduced. The static pressure distribution of the fiber optical cable spool is obtained both in theory and experiment. Theoretical simulations coincide with experimental results. This technology provides us a real-time method to monitor the inner pressure among the fiber cable layers during the optical cable winding process. | |||||||||

| Abstract: The sparse representation of image based on overcomplete dictionaries is a new image representation theory. Using the redundancy of over-complete dictionaries can effectively capture the various structure detail characteristics of an image, so as to realize the efficient representation of the image. In this paper we propose an infrared image de-noising algorithm based on K-SVD over-complete dictionaries learning using the overcomplete dictionary image sparse representation theory. The experimental results compared with the common de-noising algorithm processing results prove the effectiveness of the proposed method. |

| Abstract: A three dimensional geometric model of a homemade selective laser sintering (SLS) system is simplified and imported into Ansys Finite Element Software for static and modal analysis. The analysis results show that the supporting base that holds up the laser system undergoes large deformations. The machining accuracy can hardly meet the high-precision requirements of sintered parts with complex internal and external geometries. A method is put forward for the structural optimization of the SLS system. The calculation results show that the bending deformation of the supporting base decreases by 73.2%, and the maximum stress also decreases significantly. It indicates that the high precision manufacturing can be achieved with the improved SLS system. | |||||||||

| Abstract: We experimentally demonstrate an all-fiber method to generate a high-quality femtosecond pulse train with a repetition rate of 40GHz. A continuous wavelength laser together with an intensity modulator is used to generate an initial pulse train with a repetition rate of 40GHz. Highly nonlinear fiber (HNLF) together with single mode fiber is utilized to compress the initial pulse from 7.8ps to 985fs. The autocorrelation trace has a good sech 2 profile with no pedestal. This pulse source has a potential to be multiplexed to a higher repetition rate for its narrow pulse width. This method is high-quality, cost-effective and can be easily integrated with the fiber system. | ||||||

| Abstract: An exponential doping NEA InGaAs photocathode is theoretically proposed to apply in the near infrared streak camera. The photocathode time response is calculated and analyzed by using a photoelectron non-steady method. The numerical results show that the excited electrons in the In GaAs active layer is accelerated due to the built-in electric field induced by the exponential doping structure, which shortens the transport time of minority carriers in the photocathode and thus, the time response is greatly improved. In addition, the exponential doping InGaAs photocathode possesses time response of less than 10 picoseconds and near-infrared quantum efficiency of 10%. | |||||||||

| Abstract: High power semiconductor laser arrays have found increased applications in many fields. In this work, a hard soldering microchannel cooler (HSMCC) technology was developed for packaging high power diode laser array. Numerical simulations of the thermal behavior characteristics of hard solder and indium solder MCC-packaged diode lasers were conducted and analyzed. Based on the simulated results, a series of high power HSMCC packaged diode laser arrays were fabricated and characterized. The test and statistical results indicated that under the same output power the HSMCC packaged laser bar has lower smile and high reliability in comparison with the conventional copper MCC packaged laser bar using indium soldering technology. | ||||||

| Abstract: Particle stacking structured SiO2 porous films were prepared by sol-gel method. A model has been established to analyze the heat conductivity of these films. It is assumed that the heat energy mainly transfers through particles and their contact points. In particle stacking structured materials, a particle contacts with twelve contiguous particles, and forms twelve heat conduction branches. This model is suit to the conditions that: the size of particles in the porous material is uniform; heat conductivity of particle skeleton is much greater than particle clearance; and all contact area between particles approximately equal. The results show that: heat conductivity of particles stacking porous material is anisotropic, material heat conductivity depends on that of the particle skeleton and the ratio between radiuses of particle contact area and particle itself. |

| Abstract: Laser cladding has become a useful tool in material processing for improving the surface properties of the substrate material, and has been widely used in industry in recent years. In this paper, we studied the 3000W CW laser cladding system based on the high power diode lasers. The beam control method was proposed to reduce the collimated beam pointing errors caused during the packaging of the laser stack. At an input current of 84A, the output power and the optical coupling efficiency of this laser cladding system were 3738W and 93.7%, respectively, and at work face the beam spot size was 2.5mm*7.9mm with symmetry intensity distribution. The laser cladding system was also used in cladding the nickel powder onto the iron substrate and the nickel powder can be clothed onto steel plate uniformly. |

| Abstract: The principle of full aperture backscatter station (FABS) is introduced. For division of stray lights and convenience of assembly, optimization of optical design is available. The measurement system utilizes off-axis parabolic mirror to collect backscattered light and plane mirrors are used to replicate optical path to make assembly space compact. In order to avoid high energy backscattered light ionize air, spatial filter is available to create vacuum environment. The tilt of final optics assembly and adjust aperture of spatial filter can result in division of stray light. Separate spectrum calibration is undertaken in both stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS). The calibration system achieves precise measurement data of backscattered light energy and spectrum. | |||||||||

| Abstract: A three-dimensional kinematic model of spherical mirror is developed by coordinate transformation theory. Based on the model and Preston equation, material removal rate for polishing with constant pressure can be obtained. Then the fitted parameters are determined for special process tools (pentagon tool and Uniform Removal Tool), Conclusions beneficial to glass polishing in practice are arrived. The simulate results can describe visually the material removal law of mirror under so many kinematic parameters. The work discussed above is of importance to polish flat mirror, spherical mirror and aspheric mirror with one-axis polisher. | ||||||

| Abstract: The Long Slit Spectrograph is one of instruments onboard The World Space Observatory-Ultraviolet. Both the FUV (102-1700nm) and NUV (160-320nm) channels of LSS choose micro-channel plates (MCP) detector with anode readout in the focal plane. The MCP detectors with anode readout are typically used to provide photon counting imaging. According to the desired performance of LSS, the Vernier anode may be the optimum readout scheme. The Vernier anode is famous for its high spatial resolution, however, the original decode algorithms of the Vernier anode is susceptible to wrongly decode, when the charge acquisition is not precise enough and the footprint size of charge cloud collected by Vernier anode is not small enough and eventually results in the deterioration of photon counting image. In this paper, the causes leading to image deterioration is analyzed. The least-squares method was used to calculate the phase value to correct imaging distortions caused by charge measurement accuracy. The area ratio of each electrode covered by charge cloud is accurately calculated to improving the imaging results. The corrected algorithms are verified by experimental results and the results show that the correction methods can obviously improve the quality of the original photon counting image. | ||||||||||||

| Abstract: We introduce a new framework for image classification that extends beyond the window sampling of fixed spatial pyramids to include a comprehensive set of windows densely sampled over location, size and aspect ratio. To effectively deal with this large set of windows, we derive a concise high-level image feature using a two-level extraction method. At the first level, window-based features are computed from local descriptors (e.g., SIFT, spatial HOG, LBP) in a process similar to standard feature extractors. Then at the second level, the new image feature is determined from the window-based features in a manner analogous to the first level. This higher level of abstraction offers both efficient handling of dense samples and reduced sensitivity to misalignment. More importantly, our simple yet effective framework can readily accommodate a large number of existing pooling/coding methods, allowing them to extract features beyond the spatial pyramid representation. | ||||||||||||||||||

| Abstract: Adopting the advantages of contourlet such as multiscale, localization, directionality and anisotropy, a multifocus image fusion algorithm based on contourlet transform is developed [1]. Source images are firstly decomposed to domain of the contourlet transform. The image fusion is then implemented in subbands with different scale and direction combining. The fusion rule with maximum absolute value coefficient is used to fuse the high frequency subbands, while the rule dependent on the image's spatial frequencies and contrast are applied to the low frequency subbands. Finally the fused image is obtained through inverse transform. Experimental results show that the fused image using this algorithm has better subjective visual effect, and is better than the one using traditional Laplacian pyramid algorithm and wavelet based algorithm. | |||||||||

| Abstract: The fusion of low-light-level image and infrared image can increase the reliability of interpretation since it combines the complementary information in multispectral images, and that a color fused image can improve human observer performance and reaction times. To obtain a color night vision image by dual band sensors (visible and infrared), we first adopt the false color fusion scheme by principles of biological opponent-color vision, then transfer the first order statistics of a natural color image (target image) to the false color fused image in a perceptually decorrelated YCbCr color space. In order to give prominence to targets and details in the result, we produce a grayscale fused image using principal component analysis of the visible and infrared images, and substitute it for the Y component during the color transfer procedure. Finally, we illustrated an example of the whole fusing process. The realistic, colorful and natural fused image demonstrates validity of the method. |

| Abstract: A space telescope containing two CCD cameras is being built for scientific observation. The CCD detectors need to operate at a temperature below -65 degrees C in order to avoid unacceptable dark current. This cooling is achieved through detailed thermal design which minimizes the parasitic load to 2Kx4K array with 13.5 micron pixels and cools this detector with a combination of thermo electric cooler(TEC). | |||||||||

| Abstract: Accurate remote clock synchronization is the backbone of applications such as high-accuracy satellite navigation, digital and/or cryptographic communication systems, space-based interferometric surveillance, coherent distributed-aperture sensing at high frequencies, and geolocation. During the last decade, several clock synchronization schemes have been proposed based on quantum mechanical concepts. Quantum clock synchronization promises more precision and better security. In this paper, the various proposed quantum clock synchronization schemes are reviewed. We compare and discuss several different quantum clock synchronization schemes. The advantages and disadvantages of these schemes are investigated with emphasis on the application in space-based satellite navigation systems. |

| Abstract: Ghost imaging (correlated imaging) has been extensively investigated in recent years, both theoretically and experimentally. By using the second-order or high-order coherence properties of light field and the correlation measurement, ghost imaging was realized with quantum entangled light, pseudo-thermal light and even true thermal light. In this work, basing on the theory of statistical optics, we model the dynamic process of thermal variation, and obtain the ghost interference and ghost imaging by means of simulated calculation. In the later experiment, a pseudo-thermal source is firstly prepared by using a laser beam to pass through a rotating ground glass plate, and the parameters of the pseudo-thermal source are obtained via Hanbury-Brown-Twiss (HBT) experiment. With the pseudo-thermal light, we perform ghost interference. The experimental results demonstrate the accordance of numerical prediction. And our conclusion shows that the quality of ghost interference is influenced by the size of the pinhole in the reference path, the little pinhole due to a higher quality of ghost interference. | ||||||

| Abstract: The impact of phase noise induced by amplified spontaneous emission and nonlinear Kerr effect is analyzed in investigating the performance of BPSK homodyne systems based OPLL in long-haul optical fiber communications. Under the Gaussian probability density function assumption the equivalent power spectral density of linear and nonlinear phase noise are determined, respectively. Using the power spectral density function the expressions of phase error variance taking into account linear phase noise, nonlinear phase noise and shot noise of corresponding photodiodes are determined. The impact of the number of amplifiers, bit rate and signal power on the phase error variance is analyzed. Using the minimum phase error variance and corresponding BER expression the receiver sensitivity and BER curves are given, respectively. Under the required BER, it is shown that there is a limitation on the maximum transmission distance of the BPSK homodyne system based OPLL. The theory expressions and numerical results obtained in this paper are helpful for designing OPLL and evaluating the impact of phase noise on the receivers based OPLL in long-haul optical fiber communications. | ||||||||||||

| Abstract: This paper describes an effective method for the measurements of large aperture sampling grating, the sampling efficiency the sampling focal length and the sampling angle. By using a 351nm collimation laser source to scan the full aperture of the sampling grating in every subregion, the diffraction power of "0" order and "+1" order can be obtained synchronously by two standard integrating balls, And then by, calculating the sampling efficiency of this subregion and splicing the acquisition data, we can get the averaged grating sampling efficiency in the full aperture. Based on this method, we can effectively eliminate the effect of the output instability of laser source, decrease the uncertainty of test results. According to the fabrication principle of the sampling grating, measurements for the sampling focal length and the sampling angle can be performed. Test rersults indicate that this method can be used to measure large aperture sampling gratings | |||||||||

| Abstract: In this paper, the Allan variance technique is used in analyzing the output signal of a fiber optic gyroscope, by which the characteristics of the noise terms in the angular velocity data was determined. Then we process the random drift data of the FOG with a Kalman Filter based on the theory of time series analysis. On the other hand, an LMS adaptive filter is also applied to the random drift data. Comparative analysis on the filtering effect and their advantages and disadvantages of both algorithms is carried out. The results show both algorithms has a certain role on suppressing the random drift of the gyroscope, and the LMS adaptive filter is more effective and has a better adaptability in practice. | ||||||

| Abstract: Estimating missing values in visual data is a challenging problem in computer vision, which can be considered as a low rank matrix approximation problem. Most of the recent studies use the nuclear norm as a convex relaxation of the rank operator. However, by minimizing the nuclear norm, all the singular values are simultaneously minimized, and thus the rank can not be well approximated in practice. In this paper, we propose a novel matrix completion algorithm based on the Truncated Nuclear Norm Regularization (TNNR) by only minimizing the smallest N - r singular values, where N is the number of singular values and r is the rank of the matrix. In this way, the rank of the matrix can be better approximated than the nuclear norm. We further develop an efficient iterative procedure to solve the optimization problem by using the alternating direction method of multipliers and the accelerated proximal gradient line search method. Experimental results in a wide range of applications demonstrate the effectiveness of our proposed approach. | ||||||||||||||||||

| Abstract: In real-time imaging applications, the auto-focus algorithm and hardware structure must be adapted to the limited resources for fast and accurate real-time auto-focusing. In this paper, to obtain more precision, a new clarity evaluation function base on image's edge energy is proposed. Then, we present the corresponding FPGA hardware implementation which has simple structure. Additionally, utilizing the prior knowledge during the climbing process, a new climbing algorithm for the auto-focus which has the random start point is proposed. The experiment results show the proposed auto-focus algorithm can reduce the steps during the climbing and accelerate the auto-focus speed simultaneously. | |||||||||

| Abstract: Reconstruction- and example-based super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual details while example-based methods sometimes introduce unexpected details. Given a generic LR image, to reconstruct a photo-realistic SR image and to suppress artifacts in the reconstructed SR image, we introduce a multi-scale dictionary to a novel SR method that simultaneously integrates local and non-local priors. The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local area. The non-local prior enriches visual details by taking a weighted average of a large neighborhood as an estimate of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate that the proposed method can produce high quality SR recovery both quantitatively and perceptually. | |||||||||||||||||||||

| Abstract: This paper presented a new run-length encoding based method of extracting features from multi-target image. The algorithm uses linked list structure to store data. The data are comprised of three parts, the message in run length, the equal values and the features of the image, which are in one-to-one mapping. While scanning, we only record the features of the image according to the label. After scanning the last pixel, we merge the linked list which contains the features of image according to the equal list. Compared with other approaches, the proposed one is faster and simpler, especially it can label the binary image exactly, no matter how complicated the image is. | ||||||

| Abstract: Compared with normal reflecting scanning transform Spectrometry, cube-based Spectrometr is a key component in the time-based modulation interference spectrometer, it have more compact structure,using less accessory, easy to fix up, more steadily and more practicality. Calculations on optical path difference (OPD) of spectrometry play an important role in analyzing and improving of the structure. Following the law of Malus and the geometrical relationship of model, get the formula of OPD and the affective factors. The calculation results demonstrate that OPD is closely related to the tilted angel of rotating reflector, the size of cube reflector and the refractive index of reflector. And this kind of spectrometry has the character of high resolution, especial in some spectrum. | ||||||

| Abstract: How to implement high accuracy measurement of large-aperture coaxial optical system is crucial to the optical alignment and optical property evaluation. The methods of image quality measurement including interferometer-collimating testing, wave front testing by using Hartmann, image processing and analysis of out-of-focus image were introduced. Both the advantages and disadvantages of the three methods were compared, which showed that the alignment method based on interferometer-collimating testing is the one with the highest accuracy. The method of computer-aided alignment (CAA) based on interferometer-collimating was discussed in detail. By using a ZYGO interferometer, interferograms with different field of views and a series of Zernike coefficients were obtained to express the disalignment of the system, and then these incorrect parameters were calculated by CAA algorithms. An alignment experiment of coaxial three-mirror system with 4m focal length and 500mm aperture was carried out. The RMS value of the system is lower than 0.07. after iterations, which is close to the optical diffraction limit, proving the effectiveness of CAA method in alignment guidance. | |||||||||

| Abstract: A hexangular lattice dual-concentric-core photonic crystal fiber is proposed, which is composed of an inner core to be formed by missing a central air-hole, an outer ring core to be produced by reducing the size of the air-holes of the third ring and the double cladding circle air-holes along the direction of fiber length. Based on the full vector finite element method with anisotropic perfectly matched layers, its dispersion, leakage loss and mode field area are numerically investigated. Numerical results indicate that the proposed fiber shows large negative dispersion, strong confinement ability of guide mode, large effective mode area and low leakage loss and low sensitivity to the structure parameters. And the wavelength of high negative dispersion value can be adjusted by artificially choosing the parameters of the proposed PCF, such as Lambda, d(1) and f. The optimal design parameters with Lambda=1.2 mu m, f=0.92, d(1)=0.52 mu m for proposed PCF are obtained to achieve ultra-narrowband negative dispersion value for dispersion compensation. For the optimal design, the dispersion value reaches as high as -3400 ps.km(-1) nm(-1) and the dispersion slope value is between -1000 similar to -6000 ps.km(-1) nm(-2) over C band (1.53-1.565 mu m). At wavelength of 1.55 mu m, the leakage loss is closed to 10(-2) dB.m(-1) and the corresponding area of effective mode is 36 mu m(2). | ||||||||||||||||||

| Abstract: The observation of an object traditionally relies on the scale of optical system and the resolution is often limited by the diameter of telescope. Based on the laser interference technology, we adopt a new signal sampling method with which we sample the spectrum information by laser beat frequency. The overlapped beams interfere together and generate a series of fringes across the target. Different spectrum components of target are sampled by fringes with different spatial frequency. Then we will reconstruct the target image through inverse Fourier Transform. This method break through the difficulty that observation resolution was limited by the scale of optical system.

| Abstract: With the continuous increase of the output power of semiconductor laser array, the heat generation in the active region also increases continuously, which influences the performances and lifetime of semiconductor laser array seriously. In order to improve the performances and lifetime, understanding of the thermal behavior of high power semiconductor laser array packages and optimizing the thermal performance are crucial. By means of numerical analysis, a three-dimensional thermal model has been established, and the static and transient thermal characteristics in continuous-wave (CW) and quasi-continuous-wave (QCW) modes also have been studied systematically for a hard solder, conduction-cooled-packaged 808nm semiconductor laser array. Based on the thermal modeling and analysis, the approaches to reduce thermal resistance have been proposed. The results show that: compared with copper-tungsten (CuW), adopting the copper-diamond composite material as the submount can decrease the thermal crosstalk behavior between emitters, and reduce the thermal resistance by about 30%. In addition, a novel thermal design for the packaging structure of the mounting heat-sink is demonstrated, which has the ability of reducing the thermal resistance of the devices significantly. |

| Abstract: In this paper, an extended cubic phase mask used to realize wave-front coding technique is derived in frequency domain. Then by splitting and re-combining the terms of the phase function, a new mask containing two conjugate cubic terms is generated and can be physically realized by shifting and superposing two cubic phase mask having relative displacement with respect to the center of the pupil plane. Simulation results indicate that this phase mask has the capability of changing the system effective bandwidth while maintaining the defocus invariance characteristic. The work reported can be extended to other phase masks and could be considered to be complementary to the existing researches. |

| Abstract: Based on optical zooming used to capture images with variable resolution and field of view (FOV), an all-reflective non-coaxial optical zooming system without moving elements is designed for space camera application. In this prototype design, a deformable mirror (DM) whose curvature radius can be changed is introduced. By carefully selecting the optical power of conventional reflective mirrors surrounding the DM, the overall focal length of the imaging system can be greatly changed with slight variation of curvature radius of DM. The focal length of the system can be changed from 48mm to 192mm and the system performance is approaching diffraction-limited with diverse criteria and the maximum stoke of DM is still within its physical limits at the same time. The experimental results prove the effectiveness of DM based optical zooming and will provide a new routine for new type of space camera design in the future. | ||||||

| Abstract: This paper analyzes the relationship between the parameters of CFH (Cosine Flexure Hinge) and the adjustable angle in the measurement and micro-adjustment of yaw, pitch and roll angle in the DCM (Double Crystal Monochromator). We derive the motion equations of CFH during the measurement and adjustment process, and get accurate expression formulas. Then we use ANSYS software to simulate the CFH and compare the simulation value and the theoretical value. It shows that the maximum angular deflection error is less than 3.5 percent. We compare the CFH to the RCFH (Right Circular Flexure Hinge); and get that the maximum angular deflection theta(y) and the linear displacements of RCFH are all about 1.56 times than the CFH when the parameters are equivalent. Therefore, we provide a simple flexure hinge to improve the stability and accuracy of angular measurement and micro- adjustment in the DCM. | ||||||

| Abstract: Multi-frame super-resolution reconstruction aims to fuse several low resolution images into one image with high optical resolution. In this paper, a new regularization-based multi-frame image super-resolution algorithm is presented. Utilizing the gradient directional information, the proposed algorithm uses the gradient vector flow to measure the gradient consistency between the high-resolution image and low-resolution images. Experiment results show that the proposed algorithm achieves better performance than other multi-frame image super-resolution methods. |

| Abstract: A two-beam pumped Ti:sapphire laser with femtosecond and picosecond cavities was manufactured. Three operating modes, independent self mode-locking, cross mode-locking and multi-pulse operating, were achieved. In the independent self mode-locking mode, femtosecond and picosecond laser pulses were generated in the two cavities, respectively. In the cross mode-locking mode, synchronized femtosecond and picosecond laser pulses were obtained in the two cavities. In the multi-pulse mode, multi-pulses were produced in the picosecond cavity. The results show that, the independent self mode-locking mode is dominated mainly by group velocity dispersion and self-phase modulation, the cross mode-locking mode is governed primarily by cross-phase modulation and the multi-pulse operating is ruled largely by self-amplitude modulation. | ||||||

| Abstract: Two coupled axially phase-matched parametric four-wave mixings have been achieved in Rb vapor by using broad bandwidth laser pulses. Coherent radiations at 420 nm produced by difference-frequency optical wave mixing processes were detected and a pump-probe scheme was employed to record time varying characteristics of the parametric four-wave mixing signals. Quantum beatings at 608 cm(-1) and 70 cm(-1) were retrieved from the time varying signals by Fourier transform. Moreover, time dependent Fourier transform was utilized to analyze the dynamics of quantum beatings. The results indicate that two wave packets associated with the two quantum beating frequency components interact strongly and the quantum beating dynamics can be controlled by adjusting Rb number density. | |||||||||

In this work, the parameterization method of accumulated chord length is used to construct the knot vector. The tangent vector is chosen as the boundary condition. The characteristic parameters are calculated according to the key points and corresponding weights of a given curve. An example of NURBS interpolation for cranium is realized using the characteristic parameters obtained with Rhino software in a selective laser sintering (SLS) machine. The results show that the practical sintering curve is coincident with the given curve. | ||||||||||||

| Abstract: In recent years, cylindrically symmetric vector beams are widely used in many fields, such as high-resolution microscopy, micro printing and nonlinear optics et al. The intensity and polarization of cylindrically symmetric vector beams are symmetrical around the optical axis. Radially polarized beam and azimuthally polarized beam are the most common cylindrically symmetric vector beams. In this paper, first by using numerical methods it is calculated that the cylindrically symmetric vector beams can be obtained by overlapping two optical vortices or by overlapping an optical vortices with topological charge of two and a plane wave. Then, a radially polarized beam and azimuthally polarized beam were experimentally obtained by overlapping a right-circularly polarized plane light and a left-circularly polarized optical vortices with topological charge of two, which is obtained by using a reflective liquid crystal spatial light modulator (SLM) and a quarter-wave plate. The experimental results show that, by using this method, different kinds of cylindricany symmetric vector beams can be obtained very simply and easily, and could be switched to each other at video rate, and has higher energy conversion efficiency (up to 60%). |

| Abstract: Fulgide is well-known as a thermally irreversible organic photochromic compound. The fulgide films can be applied as recording materials in ordinary holography and polarization holography, which were respectively based on the photochromic and photoinduced anisotropy properties. In this report, different kinds of multiplexing holographic storage, like angle multiplexing, circumrotation multiplexing and polarization multiplexing are realized in a 3-indoly-benzylfulgimide/ PMMA film for the first time, where 5 images, 18 images and 2 images are stored at the same position of the film, and diffracted without crosstalk with each other. It is proved that 3-indoly-benzylfulgimide film has spatial resolution of 6300lines/mm, sensitivity of 2.89 X 10(-3)cm(2)/mJ at 632.8nm on the polarization direction of the exciting beam, fatigue resistance of 70 times, thermal stability of 14 months and has advantages like low cost, easy to used, rewritable, long life time at room temperature for both states, and high signal to noise ratio. Overall, 3-indoly-benzylfulgimide is a better rewritable holographic storage medium, but the fatigue resistance and thermal stability should be improved. | |||||||||

| Abstract: Photoexcitation of biased semiconductor photoconductive antennas by femtosecond pulses is the most common and convenient technique for generating strong terahertz (THz) pulses. In this paper, we use the three-dimensional (3D) finite-difference-time-domain (FDTD) to analyze electric field distribution of THz pulses in the near-field from a photoconductive antenna. The simulation is based on solving Maxwell's equations and the carrier rate equations simultaneously on realistic dipole antenna structures. The 3D FDTD simulation gives detailed features of THz electric field distribution in and out of the antenna. It is found that the difference of near-field distribution between the substrate and free space is considerably large. The fields of the alternating-current dipole exhibit an unsymmetrical distribution and a large deviation from those calculated using the simple Hertzian dipole theory. The magnitude of THz field in and out of the substrate attenuates rapidly while it holds the line in the gap center. The high-frequency components of THz radiation emission come only from the dipole antenna, while the low-frequency components are from both the center electrodes and coplanar stripline waveguide. This work can be used to optimize the design of antenna geometry and raise the radiation field power. |
