We present both experimental measurements and Monte-Carlo-based simulations of the diffusely backscattered intensity patterns that arise from illuminating a turbid medium with a polarized laser beam. It is rigorously shown that, because of axial symmetry of the system, only seven elements of the effective backscattering Mueller matrix are independent. A new numerical method that allows simultaneous calculation of all 16 elements of the two-dimensional Mueller matrix is used. To validate our method we compared calculations to measurements from a turbid medium that consisted of polystyrene spheres of different sizes and concentrations in deionized water. The experimental and numerical results are in excellent agreement.
我们展示了用偏振激光束照射浑浊介质时产生的漫反射后向散射强度图案的实验测量结果和基于蒙特卡罗的模拟。严格证明，由于系统的轴对称性，有效后向散射穆勒矩阵中只有七个元素是独立的。我们使用了一种新的数值方法，该方法可以同时计算二维穆勒矩阵的所有16个元素。为了验证我们的方法，我们将计算结果与由去离子水中不同大小和浓度的聚苯乙烯球体组成的浑浊介质的测量结果进行了比较。实验结果与数值结果非常吻合。
