混浊介质后向散射的Mueller矩阵的偏振特性分析

Polarization Analysis of Mueller Matrix for the Backscattering of Turbid Media

对典型混浊介质(Intralipid悬浊液)后向散射的Mueller矩阵进行了试验测量。基于Mueller矩阵计算的保偏度反映散射介质某点的偏振效应:接近光入射点的区域,保偏能力较强;随着距离的增加,保偏能力逐渐减弱而趋向于1;混浊介质浓度加大,将导致介质的保偏能力减弱。

The backscattering Mueller matrix of typical turbid medium（intralipid suspension） was measured.The polarization maintaining degree based on Muelle matrix reflected the polarization characteristic of certain position of turbid medium,the area close to the light incidence point had stronger polarization maintaining capacity,which gradually decreased to 1 with the extending distance to the incident point,and weakened with the increasing concentration of turbid media.
