A Monte Carlo method based on tracing the multiply scattered electric field is presented to simulate the propagation of polarized light in turbid media. Multiple scattering of light comprises a series of updates of the parallel and perpendicular components of the complex electric field with respect to the scattering plane by the amplitude scattering matrix and rotations of the local coordinate system spanned by the unit vectors in the directions of the parallel and perpendicular electric field components and the propagation direction of light. The backscattering speckle pattern and the backscattering Mueller matrix of an aqueous suspension of polystyrene spheres in a slab geometry are computed using this Electric Field Monte Carlo (EMC) method. An efficient algorithm computing the Mueller matrix in the pure backscattering direction is detailed in the paper.
提出了一种基于追踪多次散射电场的蒙特卡罗方法，用于模拟偏振光在混浊介质中的传播。光的多次散射包括通过振幅散射矩阵对复电场相对于散射平面的平行和垂直分量进行一系列更新，以及由平行和垂直电场分量方向上的单位矢量和光的传播方向所跨越的局部坐标系的旋转。使用这种电场蒙特卡罗（EMC）方法计算了平板几何结构中聚苯乙烯球体水悬浮液的后向散射散斑图案和后向散射穆勒矩阵。本文详细介绍了一种在纯后向散射方向计算穆勒矩阵的高效算法。
