Novel Algorithm for Computer-Aided Alignment of Wide Field of View Complex Optical System

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.
