论文摘要
平均路径长度不变特性是通过各向同性和均匀辐射照亮散射介质的非常重要的特性。在这里，我们调查了外部环境和其子域之间的折射率不匹配的不均匀介质的情况。通过引入平均路径长度值的折射索引的校正，不变性属性保持有效。这是辐射转移方程在经受各向同性和均匀辐射的介质中的固定溶液的结果。理论结果与报告的三维和二维介质的数值模拟结果一致。
The mean path length invariance property is a very important property of scattering media illuminated by an isotropic and homogeneous radiation. Here we investigate the case of inhomogeneous media with refractive index mismatch between the external environment and also among their subdomains. The invariance property remains valid by the introduction of a correction, dependent on the refractive index, of the mean path length value. It is a consequence of the stationary solution of the radiative transfer equation in a medium subjected to an isotropic and homogeneous radiance. The theoretical results are in agreement with the reported results for numerical simulations for both the three-dimensional and the two-dimensional media.
