【摘要】 通过合理选择光学材料和器件结构角,设计了一种对入射角不敏感的菲涅耳菱体型消色差相位延迟器。它是单元结构λ/4延迟器。计算表明:入射角变化±2.5°时,引起的相位延迟量的偏差约为0.3°,是常规菲涅耳菱体相位延迟器在同等情况下延迟量变化的1/6。更多还原

【Abstract】 This paper presents a fresnel rhomb type phase retarders that is much highly insensitive to the incident angle.It is based on the properly choosed optical material and internal reflection angle.It shows that the device is stable within 0.3° of 90° for i ±2.5°,which is nearly one sixth of the ordinary fresnel rhomb phase retarders variation.更多还原
