摘要

我们建立了一个新的Mueller矩阵的三阶近似模型,用于高散射介质后向散射极化效应的空间表征。利用Stokes-Mueller形式和Mie理论计算的散射振幅,我们能够在数值上确定矩阵元素。对聚苯乙烯微球悬浮液的二维Mueller矩阵光散射特性进行了表征,并与不同散射体尺寸、散射系数和各向异性系数g的实验数据进行了比较。结果表明,在方位和径向上都有较好的一致性。

Quantifying the properties of high scattering media with Mueller matrix
We have developed a new third-order approximation model of Mueller matrix for spatial characterization of the polarization effects in backscattering from highly scattering media. Using the Stokes-Mueller formalism and scattering amplitudes calculated with Mie theory, we are able to numerically determined matrix elements. Specific features of the 2D Mueller matrix components corresponding to light backscattered from polystyrene micosphere suspensions are characterized and compared with the experimental data for different size of scatterers, the scattering coefficient and the anisotropy factor g. The results show good agreement in both azimuthal and radial direction.
