Lately star sensor technology used in aircraft attitude measurement has become more and more popular because of its high accuracy  light weight  without attitude accumulation errors and other advantages. There are three main steps for star sensor to measure aircraft attitude  star image locating  star identification and attitude tracking. The latter two steps are based on the accuracy of star image locating. So it's critical to make efforts to advance the accuracy of star image locating. Some imaging errors  such as spherical aberration or coma aberration  also have negative effect on the accuracy of star image locating  of which the effect is necessarily reduced as well. At the beginning of this article  the structure of star sensor hardware is introduced. Secondly three methods for star image locating are described specifically  which are traditional centroid method  Gauss quadric fitting method and improved Gauss quadric fitting method. Subsequently an imaging calibration method is described for the purpose of reducing the effect of imaging errors. Finally the experiment shows that the accuracy of the star sensor is 2-arc-second. 2010 SPIE.   Expansion of interatomic distances in platinum catalyst nanoparticles 期刊论文  OAI收割 Acta Materialia, 2010, 卷号: 58, 期号: 3, 页码: 836-845 K.

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.   A spherical catadioptric telescope system based on Cooke corrector group (EI CONFERENCE) 会议论文  OAI收割 Novel Optical Systems Design and Optimization XII, August 3, 2009 - August 4, 2009, San Diego, CA, United states 作者:  Zhang J.;  Liu W.;  Zhang J.;  Zhang J. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 To obtain a number of advantages in fabrication  testing and alignment  many designs in which spherical mirrors replace classical Cassegrain-form aspheric mirrors are present in the literature. However  spherical mirrors suffer from substantial spherical aberration and thereby require some form of corrector group. But in this case  the question encountered is that of making the basic optical configuration more complex. In this paper  a new design based on Cooke corrector group is presented for eliminating spherical aberration  which is believed to provide higher performance with less complexity than previous approaches. Besides  the cost and fabrication period will be extremely decreased. The telescope system using corrector group here can achieve good optical performance with f# of 10  full field of 0.5  obscuration of 1/3 and MTF (Modulation Transfer Function) of 0.48 corresponding to 50@lp/mm. 2009 Copyright SPIE - The International Society for Optical Engineering.
