Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。

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。
