针对多因素影响下偏振光在散射介质中的一般传输特性，系统分析了入射光波长、介质厚度、粒子参数和入射光偏振态等物理属性对偏振光子传输特性的影响。采用蒙特卡罗方法，追踪每个光子的偏振态变化，通过统计分析偏振度变化曲线得到光经过多次散射后的斯托克斯矢量和偏振信息，并对偏振光在散射介质中的传输规律进行分析。仿真实验表明相对于波长比较大的粒子对入射光的偏振态改变较小；线偏振光能较好地保持自身偏振态；圆偏振光能够在较短时间内重新恢复自身偏振状态，粒子半径越大恢复能力越强，并且在向前传输的过程中其旋转方向会发生改变。

To study the general traveling properties of polarized light in the scattering medium with the influence of multi-factors, the influence of wavelength, medium thickness, particle parameters and incident polarization state on transmission properties of polarized photons is analyzed systematically. The Monte Carlo method is adapted to track polarization state changes of each photon, and the Stokes vector and polarization information after multiple scattering are obtained through statistical analysis of the polarization curve, and the traveling rules of polarized light in scattering medium are analyzed. Simulation results show that the particles with relative larger scale parameter have smaller changes on the incident light polarization state. Linear polarization light is good at keeping the polarization state. Circular polarization light can restore the polarization state in a short time. The larger the particle radius is, the stronger the recovering ability is, and the direction of rotation of the electric vector changes during the process of transmission.
