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.   Left conjugate gradient method for non-Hermitian linear systems 期刊论文  OAI收割 NUMERICAL LINEAR ALGEBRA WITH APPLICATIONS, 2008, 卷号: 15, 期号: 10, 页码: 891-909 作者:  Wang, Li-Ping;  Dai, Yu-Hong   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/07/30 left conjugate direction method  left conjugate gradient method  non-Hermitian linear system  breakdown  block left conjugate gradient method   Study on semi-conjugate direction methods for non-symmetric systems 期刊论文  OAI收割 INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, 2004, 卷号: 60, 期号: 8, 页码: 1383-1399 作者:  Dai, YH;  Yuan, JY   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 non-singular matrix  linear system  semi-conjugate direction  left conjugate direction  left conjugate direction method  left conjugate direction method  existence  breakdown  limited-memory left conjugate direction method  conjugate gradient method
