散射 偏振传输特性 矢量辐射传输 蒙特卡罗仿真 海雾环境 scattering polarization transmission characteristics vector radiation transmission Monte Carlo simulation sea fog environment
摘要
使用Stokes矢量表征光子的偏振状态,基于Mie散射理论计算出Muller矩阵,并将该矩阵用于体现海雾粒子的散射特性,利用蒙特卡罗方法求解海雾环境下的矢量辐射传输问题,从而模拟光子在海雾粒子中的散射情况。研究讨论了不同海雾粒子半径下,透射率和反射率随传输距离的变化情况,以及不同入射光偏振态及不同波长的入射光条件下,偏振度随海雾能见度的变化情况。该仿真实验结果为光在海雾粒子中偏振传输特性的研究提供了有益参考。
Abstract
To simulate the scattering of photons in sea fog particles, in this study, we use a Stokes vector to describe the polarization state of the photons, Mie scattering theory to calculate the Muller matrix and reflect the scattering characteristics of sea fog particles, and the Monte Carlo method to solve the vector radiation transmission problem in the sea fog environment. This paper discusses the changes in transmittance and reflectance with the transmission distance for sea fog particles of different radii, and the changes in the degree of polarization with sea fog visibility under different incident light polarization states and different incident light wavelengths. The results of the simulation experiment presented in this paper provide useful reference for research on the polarization transmission characteristics of light in sea fog particles.
