摘　　要：文中以典型偏振蒙特卡罗模型为基础,引入了一种介质浓度系数的表征方法,设计实现了一个光在不同浓度介质中散射传输的三维仿真系统,分析了引入浓度系数方法的可行性,并讨论了光在不同浓度介质中散射传输的偏振特性影响.仿真实验结果表明,文中方法实现了散射介质浓度的表征.散射介质浓度对斯托克斯矢量各分量强度和偏振度有着直接影响;斯托克斯矢量各分量的强度随散射介质浓度增加呈近似指数衰减;光在散射介质中传输后,偏振度随浓度系数变化总体趋势呈"倒N"型.Based on typical polarization Monte Carlo model, this paper proposed a media concentration coefficient representation, and developed a 3D simulation system of the light scattering transmission in the different concentration media. The feasibility of the concentration coefficient, and the polarization properties of light scattering and transmission in the different concentration media are further analyzed. Simulation experimental results showed that, the proposed method can be used to represent the scattering media concentration coefficient in the typical polarization Monte Carlo model. Scattering media concentration directly affects the intensity of each component of the Stokes vector and degree of polarization. Each component intensity of Stokes vector is approximate to the exponential decay as the media concentration increases. Polarization degree is ＂inverted N＂ as the concentration coefficient increases during the light transmission in the scattering media.
