Astigmatism induced by mirrors may significantly compromise image resolution. To solve this problem  we induced algebraic expression of astigmatism in panoramic imager based on generalized Coddington equation and theory of geometric optics. Then  we propose an optimization process for mirror profile design to eliminate astigmatism and provide purposely-designed projection formula with aid of MPGA. A series of polynomial expressions of aspherical surfaces are obtained and procedures of the design are presented. In order to facilitate ray tracing and aberration calculation  even asphere surface model is obtained by using of hybrid schemes combining MPGA and damped least squares. Finally  a prototype of the catadioptric panoramic imager has been developed and panoramic ring image is obtained. 2009 SPIE.   Modified fixed-point equations and related iterative methods for variational inequalities 期刊论文  OAI收割 COMPUTERS & MATHEMATICS WITH APPLICATIONS, 2004, 卷号: 47, 期号: 6-7, 页码: 913-920 作者:  Xiu, NH;  Wang, YJ;  Zhang, XS   |  收藏  |  浏览/下载：11/0  |  提交时间：2018/07/30 variational inequalities  fixed-point equation  projection  iterative method   Projection and contraction methods for semidefinite programming 期刊论文  OAI收割 APPLIED MATHEMATICS AND COMPUTATION, 1998, 卷号: 95, 期号: 2-3, 页码: 275-289 作者:  Han, QM   |  收藏  |  浏览/下载：23/0  |  提交时间：2018/07/30 semidefinite programming  linear programming  projection and contraction method  projection equation
