摘要

根据偏振度测量原理推导了相干矩阵中各个参数的测量公式，主要是复参量的实部与虚部．基于MachZehnder干涉装置搭建了散射体偏振度测试平台，并对同一粒径不同浓度散射体的偏振特性进行了测试．结果表明：浓度为0.006 25%的聚苯乙烯（Polystyrene

PS）散射介质光散射较弱，偏振度值高达0.992，散射体具有良好的保偏特性；随着聚苯乙烯散射介质浓度增大到0.025%，光散射增强，偏振度值降至0.545，散射体的退偏效果显著．

Abstract

In this paper

the measurement formula of each parameter in the coherent matrix is derived according to the principle of polarization measurement

which is mainly the real part and the imaginary part of the complex parameter. Based on the Mach-Zehnder interference

the platform is built to measure the degree of polarization of the scatterers

at which the polarization properties of the scatterers of the same particle size and different concentrations are tested. The experimental results show that the light scattering of the polystyrene medium with a concentration of 0.006 25% is weak

and the value of the degree of polarization is as high as 0.992

and the scatterers has good polarization-maintaining properties. As the concentration of the polystyrene scattering medium increased to 0.025%

the light scattering was enhanced. When the value of the degree of polarization decreased to0.545

the depolarization effect of the scatterers was remarkable. The measurement method and device provide an idea for directly measuring the degree of polarization by using a coherence matrix.
