摘要

消光比和探测器噪声是决定纳米线栅偏振成像偏振精度的两个重要参数。为解决两参数在系统优化时的取值问题，本文建立了两参数与偏振噪声的数学模型，采用像元组接收光电子数作为衡量探测器噪声与系统偏振噪声的桥梁量化了两者关系。仿真分析比较了两参数在入射光偏振态变化时对偏振噪声的作用。然后搭建消光比和曝光时间可调的偏振成像系统精度实验平台，验证该数学模型和仿真结果。仿真与实验共同表明，系统消光比大于20后，通过提高像元组接收的光电子数以抑制探测器噪声要比继续提升消光比对提高系统偏振精度的贡献大。

Abstract

In remote sensing imaging

extinction ratio and detector noise are important parameters that determine the accuracy of polarization imaging of nanowire gratings. To strike a balance between the two parameters for system optimization

a mathematical model using the two parameters and polarization noise was established in this paper. The photoelectron number received by large pixels was used as a measure to quantify the relationship between detector noise and system polarization noise. The effect of the two parameters on polarization noise was compared via a simulation wherein the polarization state of incident light was changed. Then

a platform to test the accuracy of polarization imaging with adjustable extinction ratio and exposure time was built to verify the mathematical model and simulation results. The simulation results demonstrate that when the extinction ratio of the system is greater than 20

wherein increasing detector noise by increasing the number of photoelectrons received by large pixels makes a greater contribution to the polarization accuracy than increasing the extinction ratio.
