单透镜系统的偏振像差

The Polarization Aberration of Single Lens System

基于Fresnel原理,借助Jones矩阵理论,经相应推理导出任意单色光通过单透镜前后入射光束与出射光束偏振方向的偏转角的变化的一般表达式并诠释其物理意义。采用偏振光线追迹的方式,通过对单色光经透镜前后表面偏转角度的研究,给出不同入射角度对应其出射光束偏振方向偏转角度的精确解,并对其进行分析推理,得到单色光在透镜前后偏振状态的变化情况。利用计算机模拟技术,计算和分析表明:单色光经过单透镜后,偏振状态呈一定规律变化,在入射光偏振方向与入射方向和法线所在平面呈±45°角时,偏转角度最大。同时偏转程度与偏振光入射角大小成正相关。

Based on the Fresnel principle and the Jones matrix theory,the general expression and interpretation of its physical meaning of the change can be deduced,which is the polarization direction of the deflection Angle of the incident light and the outgoing light after any monochromatic light through a single lens. With the method of polarization ray tracing,the exact solutions of the polarization beam deflection Angle of the outgoing light corresponding to different incidence angles is presented through the study of the deflection Angle of the monochromatic light after lens. And the change of polarization state of monochromatic light before and after the lens is obtained by analysis of its reasoning. Using computer simulation technology,the calculation and analysis show that monochromatic light after a single lens,the polarization state changes in a certain rule,and when the angle between the polarization direction of incident light and incident Angle is 45 degree,the deflection angle is maximum. And deflection degree and polarized incident Angle is positively correlative.
