查询词典 retarder

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。
