我们提出了一个单散射模型，以及在混浊介质中的葡萄糖偏振光的影响的蒙特卡罗模型。葡萄糖改变漫后向散射和前向散射光的穆勒矩阵图案，因为葡萄糖分子旋转线偏振光的偏振平面。例如，穆勒矩阵元素S21和S12中的旋转角与葡萄糖的浓度线性相关，并且随着源-检测器距离而增加。在非扩散区，两个模型吻合得很好。在扩散区，单散射模型是无效的，但仍然存在的Mueller矩阵元素的旋转角和葡萄糖的浓度，这是由Monte Carlo模型预测的线性关系。
We present a single-scattering model as well as a Monte Carlo model of the effect of glucose on polarized light in turbid media. Glucose alters the Mueller-matrix patterns of diffusely backscattered and forward-scattered light because glucose molecules rotate the polarization plane of linearly polarized light. For example, the angles of rotation in Mueller-matrix elements S21 and S12 are linearly related to the concentration of glucose and increase with the source-detector distance. In the nondiffusion regime, the two models agree well with each other. In the diffusion regime, the single-scattering model is invalid, but there still exists a linear relationship between the angles of rotation in the Mueller-matrix elements and the concentration of glucose, which is predicted by the Monte Carlo model.
