光学系统的偏振像差分析

偏振像差是影响光学系统性能的重要因素之一,尤其对偏振有严格要求的光学系统来说更是如此。论述了偏振像差的理论和偏振光线追迹的方法,并对旋转对称光学系统、倾斜偏轴光学系统的偏振像差进行了分析,指出了薄膜设计对偏振像差所产生的重要影响。介绍了提高光学系统偏振精度的几个方法,包括尽可能的减小入射角、薄膜设计的优化和像差之间的相互平衡。

Polarization aberration analysis of optical systems

Polarization aberration is one of the most important factors affecting the performance of optical systems, especially in systems which are "polarization critical ones". Polarization aberration theory, methods of polarization ray tracing, polarization aberration analysis of rotationally symmetric optical systems, polarization aberration analysis of tilted and decentered optical systems are described. Important effects of thin film design on polarization aberrations are also discussed. Finally, several methods which can improve the polarization accuracy of any optical systems are presented, including keeping the angles of incidence as small as possible, optimizing the coating design and balancing aberrations against each other.
