摘　　要：根据米散射理论,提出了新型导光板的设计思路,计算并分析了对于一定波长的入射光,不同粒径的微粒的散射特性。总结了随着微粒粒径的变化,散射效率、消光效率与背向散射效率的变化规律,分析了散射过程中的偏振度随粒子粒径几散射角变化的情况,同时模拟计算了多个微粒对同一波长的入射光经过多次散射后的概率统计结果。Based on Mie Scattering Theory, a thought for the design of a novel light guide plate was put forward. Its scattering characteristic properties of particles with different diameters for the same entrance rays were calculated and analysesd. The law of scattering efficiency extinction efficiency and backscattering efficiency has been summarized, and polarization condition changing with scattering angle and diameter of particle in scattering processes has been disussed. At the same time, the result of how the incident light with the same wavelength to he scattered by patticles was simulated in this paper.
