通过求解三维辐射传输方程，模拟了光在生物组织等各向异性散射半无限介质中的传播，并考虑了界面处的内反射效应。应用二维傅里叶变换和修正球谐函数法，得到了相应齐次问题的解析解。所得到的解决方案用于解决边界值问题，这是重要的应用在生物医学光学领域。推导出的方程成功地验证了Monte Carlo模拟的比较。(C)2012美国光学学会
The three-dimensional radiative transfer equation is solved for modeling the light propagation in anisotropically scattering semi-infinite media such as biological tissue, considering the effect of internal reflection at the interfaces. The two-dimensional Fourier transform and the modified spherical harmonics method are applied to derive the general solution to the associated homogeneous problem in terms of analytical functions. The obtained solution is used for solving boundary-value problems, which are important for applications in the biomedical optics field. The derived equations are successfully verified by comparisons with Monte Carlo simulations. (C) 2012 Optical Society of America
