In this paper, the design, optimization and analysis of broadband full-Stokes polarimeters with immunity to both Poisson and Gaussian noise are presented. Different from the commonly-used optimization metrics such as, the condition number (CN), the equally weighted variance (EWV), or the polarimetric modulation efficiency (PME) for Gaussian noise, the optimally balanced condition for Poisson noise (BCPN) is, for the first time, proposed and used as a metric for the optimization of polarimeters. The numerical results show that the polarimeters optimized with the BCPN have immunity to both Poisson and Gaussian noise. The broadband polarimeters optimized from the BCPN are achromatic and have similar polarimetric modulation properties over the waveband, in contrast to the polychromatic polarimeters optimized from the CN, EWV and PME, whose polarimetric modulation properties vary with wavelength.
本文介绍了具有泊松噪声和高斯噪声免疫能力的宽带全斯托克斯偏振计的设计、优化和分析。与用于高斯噪声的常用优化指标（如条件数（CN）、等加权方差（EWV）或偏振调制效率（PME））不同，首次提出了泊松噪声的最优平衡条件（BCPN），并将其用作偏振计优化的指标。数值结果表明，用BCPN优化的偏振计对泊松噪声和高斯噪声均具有免疫能力。与从CN、EWV和PME优化的多色偏振计不同，从BCPN优化的宽带偏振计是消色差的，并且在整个波段具有相似的偏振调制特性，而多色偏振计的偏振调制特性随波长变化。
