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.   Method for computer-aided alignment of complex optical system (EI CONFERENCE) 会议论文  OAI收割 2nd International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 2, 2005 - November 5, 2005, Zian, China 作者:  Yu J. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 For making complex optical system meet the design requirement  such as the space camera used in remote sensing and UVX lithophotography  especially for off-axis all-reflecting optical system  alignment technology is so necessary. In this paper  a method is presented. Based on the ideas of linearity instead of non-linearity and difference quotient instead of differential quotient  a mathematical model for computer-aided alignment is proposed. This model included the characteristics of the optical system  wavefront difference of its exit pupil and its misalignment of the misaligned optical system. Then comparing self-compiled software with alignment package of CODE V  as a result  this self-compiled software is much more valid than alignment package of CODE V. For a large aperture  long focal length and off-axis three-mirror optical system  computer-aided alignment is successful. Finally  the wavefront error of the middle field is 0.094 waves RMS and the wavefront error of +0.7 field is 0.106 waves RMS and the wavefront error of -0.7 field is 0.125 waves RMS at =632.8nm are obtained.
