在最近的工作随机介质的远程成像的光，一个简单的概括适当的扩散边界条件，考虑到菲涅尔反射。在外部边界的米尔恩问题解决的折射率，吸收和散射各向异性参数的各种值产生外推端点和外推距离。导出了一个广义的界面条件来代替通常的强度连续条件。基准质量的数值结果给出的外推距离和新的指数相关参数的接口条件。当指数足够大时，使用外推终点的困难进行了讨论，并提出了一种适合这种情况的新的图像程序。(C)1995年美国光学学会
In connection with recent work on remote imaging of random media by light, a straightforward generalization of the proper diffusion boundary conditions is presented that takes into account Fresnel reflection. The Milne problem at exterior boundaries is solved for various values of index of refraction, absorption, and scattering anisotropy parameters to yield extrapolated end points and extrapolation distances. A generalized interface condition is derived to replace the usual condition of continuity of intensity. Benchmark-quality numerical results are given for the extrapolation distance and for the new index-dependent parameter in the interface conditions. Difficulties in using the extrapolated end point when the index is sufficiently large are discussed, and a new image procedure suitable for this case is presented. (C) 1995 Optical Society of America
