摘    要:在Mie散射理论的基础上分析了群体粒子散射的偏振特性,并用两种不同直径(0.26 μm,0.55 μm)的球形粒子作为散射介质进行了相关实验,比较了群体粒子散射光垂直与水平偏振光的偏振度.实验发现:散射光的偏振度随粒子直径的变化呈现出一定的规律性,直径大的粒子散射光在水平方向的偏振度小于直径小的粒子;而垂直方向的偏振度却完全相反,直径大的粒子大于直径小的粒子.

关 键 词:Mie散射理论  群体粒子散射  激光  偏振度

Abstract:In this paper,the polarization characteristic of the particle group scattering based on Mie scattering theory is analyzed, and the correlative experiment is done with two species of particle ball of different diameters(0.26μm,0.55μm). The result shows the polarity of scattering light of the bigger particle in horizontal direction is smaller than the smaller particle. On the contrary, the polarity of scattering light of the bigger particle in vertical direction is bigger than the smaller particle.
Keywords:Mie scattering theory  particle group scattering  laser  polarity
