| 摘 要： | 本文定量推导了轴上物点发出的部分偏振光通过透镜时其偏振度、偏振分量方位角和椭率角与透镜参数和入射光参量间的关系。对已知参数的透镜进行了定量计算，表明处于一定偏振状态的部分偏振光经透镜后其偏振度、偏振分量方位角和椭率角在出射光束截面上呈一定分布，产生偏振像差。给出了部分偏振光基本参量变化的数量级。指出在高精度光学测量中为避免透镜偏振像差影响，应尽可能减小光束半径和发散角。

| Abstract: | In this paper, polarization degree、 polarization light part horizontal angle and ellipticity angle of partially polarized light beam from on axis object point versusing parameters of lens and input light are deduced. Changes of these parameters on partially polarized light, which penetrate a known len, are calculated. Calculation shows polarization degree、 polarization part horizontal angle and ellipticity angle of partially polarized light beam present certain distribution on the cross section of output beam. Polarizing aberration is caused. In order to devrease inflence of porlarizing aberration, radius and divergence angle of beam ought to be decreased. |
