We perform simulations of coherent backscattering enhancement, explicitly accounting for the finiteness of spatial coherence of radiation. Three plausible models are considered, which produce the broadening of the coherent backscattering angular profile with the loss of spatial coherence. These models show fair agreement with data obtained earlier for biological media. Additionally, the exact solution for the double scattering term is obtained; its numerical magnitude is shown to be non-dominant for evaluations in the biomedical area due to high scattering anisotropy.

组织模型中的相干和低相干增强反向散射


我们对相干反向散射增强进行了模拟，明确地考虑了辐射空间相干性的有限性。考虑了三个看似合理的模型，这些模型随着空间相干性的损失而产生相干反向散射角轮廓的加宽。这些模型与之前获得的生物介质数据相当一致。此外，还得到了双散射项的精确解；由于高散射各向异性，其数值大小在生物医学领域的评估中不占主导地位。
