This work analyzes the effect of experimental errors and measurement noise on Mueller matrix channeled spectropolarimeters. The main advantage of this type of polarimeter is the independence on temporal resolution, as it can be used as a snapshot polarimeter. The simulation of the polarimeters with experimental errors and two published extraction methods of the sample Mueller matrix are also presented. The Mueller matrix channeled spectropolarimeter (MMCS) setup consists of a mirrored Stokes channeled spectropolarimeter (SCS) as the polarization states generator (PSG) and a SCS as the polarization states analyzer (PSA). The SCS setup comprises two thick birefringent retarders followed by a horizontal linear polarizer. The effects of the thickness ratio of the retarders, the global retardance factor, retardance errors, axes alignment errors, and additive Gaussian noise are further studied to optimize the MMCS setups. In this work, we do not include a calibration procedure to improve the measured Mueller matrix parameters, but we study the sensitivity of the polarimeter to different configurations and error sources.
这项工作分析了实验误差和测量噪声对穆勒矩阵通道光谱偏振仪的影响。这类偏振仪的主要优点是与时间分辨率无关，因为它可以用作快照偏振仪。文中还介绍了带有实验误差的偏振仪模拟以及两种已发表的样品穆勒矩阵提取方法。穆勒矩阵通道光谱偏振仪（MMCS）装置由一个作为偏振态发生器（PSG）的镜面斯托克斯通道光谱偏振仪（SCS）和一个作为偏振态分析仪（PSA）的SCS组成。SCS装置包括两个厚双折射延迟器，后面跟着一个水平线性偏振器。进一步研究了延迟器的厚度比、全局延迟因子、延迟误差、轴对准误差和加性高斯噪声的影响，以优化MMCS装置。在这项工作中，我们没有纳入校准程序来改进测量的穆勒矩阵参数，但我们研究了偏振仪对不同配置和误差源的灵敏度。
