界面反射偏振象差分析

在光学没计中,一般认为在同一光波面上,光束具有相同的振幅和偏振状态。事实上,光束经过许多光学元件后,偏振状态会发生变化,特别是入射角和光程的不同,会导致出射光波面上偏振分布不再均匀,形成偏振象差。本文主要就轴上物点发出的光束经过界面反射后的偏振象差方面进行了分析。

Investigation on Polarizing Aberration of Reflection Interface

In the optical design,the light beams are commonly considerated to have thesame amplitude and polarization state on one wave surface.In fact,when thelight beams penetrate a series of optical elements,the polarization states andtheir distribution are different from those of the original one,for this reason,the polarizing aberrations are produced due to the different incident angles andlight paths.In this paper,the polarizing aberration of light beam from the on-axis object,which is reflected from the reflecting surface,is analysed.
