传统上用于描述Berek和Ehringhaus旋转补偿器的操作的理论是基于几何光学的，因此是不精确的。在经典电磁理论的框架内分析旋转补偿器时，可以确定透射光的相位差和振幅比的精确解。近似解和精确解在某些有趣的方面有所不同，这在研究光的单色平面波时变得非常重要。特别是，精确解和近似解之间的差异在高入射角下变得更加明显。精确的理论预测了使用高折射率各向同性板测量相对长波长处的小相位差的可能性。
The theory conventionally used to describe the operation of Berek and Ehringhaus rotary compensators is based on geometrical optics and, hence, is not exact. When rotary compensators are analyzed within the framework of classical electromagnetic theory, exact solutions for the phase difference and amplitude ratio of the transmitted light can be determined. The approximate and exact solutions differ in some interesting ways which become of substantial importance in the examination of monochromatic plane waves of light. In particular, the discrepancies between exact and approximate solutions become more pronounced at high angles of incidence. Exact theory predicts the possibility of using a high-refractive index isotropic plate for measuring small phase differences at relatively long wavelengths.
