本文考察并观测了单个非理想四分之一波片（QWP）的归一化第三斯托克斯参数的四次方与使用平行偏振器和两个相同QWP的偏振测量装置所测得的偏振对比可见度函数之间的匹配关系。利用傅里叶模态法（FMM）从理论上研究了单个QWP的斯托克斯参数行为以及偏振对比方案的可见度函数，并在琼斯矩阵形式体系内进行了描述。随后，该分析被推广到实际情况，考虑了透射各向异性、相位偏差以及光学元件相对于其理想取向的失准。推导出了偏振对比方案可见度函数以归一化斯托克斯参数表示的解析表达式，以及以表示相位偏差、透射各向异性和偏振对比方案角度失准的小参数表示的渐近展开式。对于所研究的基于硅光栅的QWP，在200-700 GHz的几乎整个研究频率范围内，FMM计算的归一化第三斯托克斯参数的四次方与可见度函数（FMM计算值和实验测量值）之间展现了良好的定量一致性。
英文摘要
The match of the fourth power of the normalized third Stokes parameter for a single non-ideal quarter-wave plate (QWP) and the visibility function of the polarization contrast measured using a polarimetric setup with parallel polarizers and two identical QWPs was examined and observed. The behavior of the Stokes parameters of a single QWP and the visibility function of the polarization contrast scheme were investigated theoretically using the Fourier-modal method (FMM) and described within the Jones matrix formalism. This analysis was then generalized to a realistic case, accounting for the transmission anisotropy, phase deviation, and misalignment of optical components from their ideal orientations. An analytical expression for the visibility function of the polarization contrast scheme in terms of the normalized Stokes parameters was derived, along with the asymptotic expansions in terms of small parameters representing the phase deviation, transmission anisotropy, and angular misalignment of the polarization contrast scheme. For the investigated silicon-grating-based QWP, good quantitative agreement between the FMM-calculated fourth power of the normalized third Stokes parameter, and the visibility function (FMM-calculated and experimentally measured) was demonstrated over almost the entire investigated frequency range of 200-700 GHz.
