We investigate the case when light is scattered by Gaussian-correlated, quasi-homogeneous, anisotropic media. The analytical expression for the cross-spectral density function of the scattered field that is produced by scattering of a polychromatic plane wave incident upon a Gaussian-correlated, quasi-homogeneous, anisotropic medium is derived by use of a tensor method. Numerical examples are given to illustrate the normalized spectral density and the spectral degree of coherence of the field scattered by the anisotropic scatterer in contrast with that scattered by the isotropic scatterer.
我们研究了光被高斯相关的准均匀各向异性介质散射的情况。通过张量方法，推导出了多色平面波入射到高斯相关的准均匀各向异性介质上散射产生的散射场的互谱密度函数的解析表达式。给出了数值示例，以说明与各向同性散射体散射的场相比，各向异性散射体散射的场的归一化光谱密度和光谱相干度。
