摘要

为了确定非理想透镜组偏振效应和偏振片的透过轴角度误差对气溶胶偏振探测仪偏振测量精度的影响,首先,利用Jones矩阵描述透镜组的偏振效应,结合入射光相干矩阵推导了气溶胶偏振探测仪前置光学透镜组的起偏度；其次,利用Mueller矩阵方法推导了综合考虑入射光偏振态、透镜组起偏效应和偏振片透过轴方位角误差影响下的气溶胶偏振探测仪的偏振测量误差;最后,通过计算得到透镜组的起偏度和仪器的绝对偏振度测量误差。根据计算, 0.67 μm通道透镜组最大起偏度和仪器最大绝对偏振测量误差分别是0.3143和0.2838; 1.64 μm通道透镜组最大起偏度和仪器最大绝对偏振测量误差分别是0.3249和0.2937。结果显示,仪器的主要误差源是非理想透镜组的偏振效应,未经标定的气溶胶偏振测量仪存在严重的测量误差。

Abstract

To understand the effect of polarization effect of the imperfect lens components and angle error of linear polarizers on polarimetric precision of the aerosol polarimeter, firstly, the polarization degree of lens component is deducted by combining the Jones matrix of lens component with the coherent matrix of incident beam. Secondly, the polarimetric error of the instrument is estimated by using Mueller matrix, considering all effects of the polarization states of incident beam, polarization effect of lens component and the azimuth errors of polarizers. Finally, the polarization degree of lens components and the polarimetric error of the instrument are specifically computed, respectively. At the channel of 0.67 μm, the maximum of polarization degree of the lens component and absolute polarimetric error of the instrument are 0.3143 and 0.2838, respectively. At the channel of 1.64 μm, the maximum of polarization degree of the lens component and absolute polarimetric error of the instrument are 0.3249 and 0.2937 respectively. It is indicated that the major error of the polarimeter arise from polarization effect of the imperfect lens components and a great error exists if the instrument is not calibrated.
