界面反射偏振像差分析

Investigation on Polarized Aberration of A Reflected Surface

迄今为止的光学设计中,一般认为在同一光波面上,光束具有相同的振幅和偏振状志.事实上,光束经过许多光学元件后,偏振状态会发生变化,特别是由于入射角和光程不同,导致出射光波面上偏振分布不再均匀,形成偏振像差.本文主要就轴上物点发出的光束经过界面反射后的偏振像差进行了分析.

In optical designs,the light beams are commonly considerated to have the same amplitudes and polarization states on one wave surface.In fact,when thelight beams penetrate a series of optical devices,the polarization states andtheir distribution are different from that of the original,for this reason,thepolarized aberrations are produced by the different incident angles and phases.In this paper,the polarized aberration of a axial bundle reflected on the sur-face is analysed.
