摘要
本文利用光线追迹法、对双折射波片用于发散光束的相位延迟,偏振像差进行了分析,发现在与光轴夹角为45°(或致45°)的入射面上,偏振像差最小,为双折射波片用于柱面会聚光束以改善成像质量提供了理论依据。
By means of ray tracing, retaration and polarization aberration of a birefrigem wave-plate in a divergent beam are analysed. We find that the polarization aberration reduces to minimun as incident rays on the plane which makes 45° (or near 45°) with the optic axis of crystal, so the birefrigent wave-plate is an ideal retarder in cylindrical beam.
