Actual star image adding optical cross-talk effect of CMOS(Complementary Metal Oxide Semiconductor)  detector is simulated by non-sequential ray tracing in ZEMAX optical design and analysis software to evaluate its performance. The distortion relative to image spot centriod is introduced and calculated by simulated star images  which is less than 0.03% of lens in this paper. Thermal adaptability is discussed by opt-mechanic thermal analysis  which shows the RMS spot radius of marginal filed changes less than 0.7m under 10C temperature gradient  and changes less than 1m during homogeneous temperature changing from 40C to 40C. The results of analyses and simulations show the design of this lens can achieve the requirement of high precision CMOS star sensor well. 2011 IEEE.   Equivalent lenses of supersonic seeker's outflow refractive index field obtained by simulation and experiment (EI CONFERENCE) 会议论文  OAI收割 2008 International Conference on Optical Instruments and Technology: Optical Systems and Optoelectronic Instruments, November 16, 2008 - November 19, 2008, Beijing, China Qun W.; Hongguang J.; Ming X. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 In order to decrease the aerodynamic drag of supersonic image guide missile and design a non-spherical dome  the outflow field of the missile's dome is simulated using FLUENT. Based on the simulated results  the accurate density field of the outflow field at all kinds of flight conditions is obtained  and then the refractive index field of the outflow field is gotten according to the Gladstone-Dale law. The results show that the shock wave induces the heterogeneity of the refractive index field and the turbulent causes distortion. The outflow field is divided into several zones which are taken as equivalent lenses for aberration analysis. 2009 SPIE.   图像与视频拼接算法研究 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院研究生院, 2007 作者:  苗立刚 收藏  |  浏览/下载：88/0  |  提交时间：2015/09/02 图像拼接  视频拼接  显微镜图像  误差分析  文档图像  镜头失真  透视校正  视频监控  image mosaicing  video mosaicing  microscopic image  error analysis  document image  lens distortion  perspective rectification  video surveillance   Design and analysis of large spaceborne light-weighted primary mirror and its support system (EI CONFERENCE) 会议论文  OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Large Mirrors and Telescopes, July 8, 2007 - July 12, 2007, Chengdu, China Yan Y.; Jin G.; Yang H.-B. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 With the development of the resolution of spaceborne remote sensor  the diameter of the primary mirror of spaceborne telescope becomes larger and larger. The distortion of primary mirror which is influenced by the mirror material  structure  self-weight  support system and temperature environment affects optical image quality finally. In this paper  an on-axis TMA high-resolution Cassegrain optical payload with a primary mirror whose diameter is 650mm was designed and the effects of the influence factors of the distortion acts on the on-axis TMA optical system primary mirror had been analyzed by means of Finite Element Analysis. During work  the technology of the primary mirror design had been summarized and general consideration of the primary mirror design technology also had been described at the same time. Considering the telescope manufacture and work station  a reasonable and optimal structure of the primary mirror sub-assembly is taken finally. In the end  the distortion of the primary mirror during its fabrication station and work station had been analyzed by integrated Finite Element Analysis Method. The results implicated the synthesis profile error (P-V value) for the primary mirror is less than /10 and all the indexes of the primary mirror satisfy the requirements of the optical system.   Practical method of shadow detection and removal for high spatial resolution remote sensing image 会议论文  OAI收割 MIPPR 2007: Remote Sensing and GIS Data Processing and Applications; and Innovative Multispectral Technology and Applications, Wuhan, China, November 15, 2007 - November 17,2007 Ru, Li; Bing, Zhang; Xia, Zhang; Zhengchao, Chen; Zheng, Wei; Lanfen, Zheng 收藏  |  浏览/下载：22/0  |  提交时间：2014/12/07 Image analysis  Feature extraction  Image resolution  Neural networks  Remote sensing  Signal distortion
