But the field of a common reflecting system is too small to meet the needs nowadays. When a correcting lens is inserted at the rear of R-C system  the off-axis image quality is significantly improved. After optimizing with CODE V optical design software  a new design scheme of reflecting telescope with large field of view is achieved. 2009 SPIE.   Novel algorithm for computer-aided alignment of wide field of view complex optical system (EI CONFERENCE) 会议论文  OAI收割 Yang X.; Han C. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 With the advent of the new complex optical system  alignment technology is necessary. In this paper  is presented an alignment algorithm whose main idea is composed of damped least square method and singular value decomposition method. In addition  the how and why to enter the damped factor into algorithm is explained. According to this algorithm  an alignment software package was compiled and compared self-compiled software with alignment package of CODE V. Results show that  this self-compiled software is much more valid than alignment package of CODE V. For a field of view of 2 R-C system  average MTF over the field of view was greater than 0.3 at 50 line pairs /mm.   Subsolidus phase relations and crystal structures of R-Ca-Cu-O (R = Nd, Sm, Gd, Tm) systems 期刊论文  OAI收割 Journal of Solid State Chemistry, 2003, 卷号: 173, 期号: 1, 页码: 164-171 C.
