摘　　要： 采用菲涅尔原理和琼斯矩阵理论,分析了偏振光经过透镜后偏振状态的变化规律,得到了任意入射偏振光通过单透镜后偏振状态的一般表达式,讨论了偏振光通过共焦双透镜后的偏振分布。分析结果表明:对于单透镜,入射光偏振方向相对于入射面±45°时有最大的偏转量;入射偏振光在共焦双透镜作用下的偏振方向偏转量是单透镜时的2倍。 According to Frensnel law and Jones Matrix, the polarization change of polarized light passing through the convex lens is analyzed. The general expression of any polarized light through convex lens is obtained. Furthermore, the polarization distribution of polarized light beam passing through one convex lens and double confocal lenses are discussed respectively. All of those discussions are based on the extended source paralleling the optical axis. The analysis results show that for single lens, the maximal change of polarizing direction is at the angle of ±45° when incident light is related to incident flat, and the change for the double confocal lenses is twice that of one convex lens.
