We extract the pixel gray values at the image edge which distribute as a knife-edge function  and make differential calculation and Fourier transformation of it  and then we can obtain the dynamic MTF curve of the optical system. The value of the curve at the Nyquist frequency is the most important parameter that reflects the image quality. We add push-scanning imaging and environmental effects to the static MTF of space camera and compare the MTF value with the dynamic MTF at Nyquist frequency. The comparison result can help us verify the accuracy of the calculating results and the feasibility of our method.

It is the combination of multi-point forming and traditional spinning. Principle of EST is described  and plastic deformation is generated  traditional spinning method is compared with it  experimental result accords with simulation result. Feasibility of EST is validated by simulation and experimental results. (2011) Trans Tech Publications.  and characteristics of it are analyzed. Finite element analysis (FEA) model of disc-shape part is established  EST process is analyzed  equivalent stress and plastic strain distributions are analyzed. EST equipment is developed  and the experiments are made.

It extends the attacking range of Ground Based Laser (GBL) weapons enormously. Relevant researches have been carried out for many years. The structures and operating theory of the entire system consists of ground-based high energy laser weapon and space-based relay mirror. The main work of this study is focused on the analysis of relay mirror energy characteristics to deduce the relationship among the attacking range of weapon and diameter of ARMS and target irradiance. Calculation examples are also given. The results proved the strong points and feasibility of ARMS theoretically further. It is summarized that more importance should be attached to ARMS development. The results given in this paper can be reference of an actual ARMS system to some extends. 2011 IEEE.   Image motion compensation for a certain aviation camera based on Lucy-Richardson algorithm (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electronics and Optoelectronics, ICEOE 2011, July 29, 2011 - July 31, 2011, Dalian, China Zhong C.; Fu J.; Ding Y. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 According to the actual situation  when high quality and high precision are required for the image  both beforehand and afterwards compensation should be used. In this paper  we use Lucy-Richardson algorithm to compensate image motion of a certain aviation camera as an afterwards compensation. Firstly  we analyze the imaging principle of the camera and the reasons that cause image motion. Then we have a brief introduce of the Lucy-Richardson algorithm. At last  in order to show the feasibility of the method  we do some simulation. Through theoretical and practical analysis  experiments and test  we conclude the Lucy-Richardson algorithm can be used to compensate image motion for the certain camera. 2011 IEEE.   The study of encoding principle and encoding disc design of a new-style vernier absolute encoder (EI CONFERENCE) 会议论文  OAI收割 2nd Annual Conference on Electrical and Control Engineering, ICECE 2011, September 16, 2011 - September 18, 2011, Yichang, China 作者:  Li L. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 To satisfy the requirement of encoder miniaturization  high dependability  and high measuring accuracy  a new-style vernier absolute type encoder which offered significant advantages over less reticling circles and high precision was presented in the paper  which carried out the design of vernier encoding disc  the analysis of new-style vernier encoding principle  and exact encoding track calibration by studying the photoelectric encoder. The Matlab simulation results prove that the encoding and coding methods are feasible. The test showed that the cubage of encoder was quite small and the diameter of the encoder can be controlled within 100mm  its resolution can reach 24 bits i.e. 0.0772. The feasibility of encoding and coding method was further proved. 2011 IEEE.
