光学系统像面强度的偏振分析

引入偏振像差矩阵的概念，描述光学系统的偏振像差，建立了光学系统的偏振像差矩阵和复振幅响应矩阵之间的关系，并推导出光学系统像面强度的分布函数和入射光的偏振度以及光学系统的平均线偏振灵敏度的成积成正比。最后，以航天光学遥感器中常用的卡氏望远镜以及扫描系统为例，计算并分析了入射光的偏振度和光学系统的平均线偏灵敏度对像面中心点强度的影响。

Polarization analysis of image-plane intensities of optical system

Presents the polarization aberration matrix to describe polarization aberration of optical system and the interrelation between polarization aberration matrix and response matrix of complex amplitude established and the equation of intensity spread function of optical system in image plane deduced, and concludes from the theoretical result that the intensity at the central point is directly in proportion to the average polarization sensitivity and the polarization performance of incident light. Illustrates the effect of polarization on the intensity of image plane with an example of calculation.
