多散射介质中光子密度波扩散方程的求解

Solution of diffusion equation in multiple-scattering media with photon densing wave

摘要: 将光源作为一个复数点光源,根据实验研究模型的要求,求解了多散射介质中光子密度波扩散方程,找出了与入射面相对应面的光子通量和介质中吸收系数改变量之间的关系。所得结论能直接用于多散射介质中成像问题的实验研究之中,即通过对光子通量的检测,反演出吸收系数改变量的分布,从而达到多散射介质中的成像问题的解决。

Abstract: In this paper,we consider the general situation in which a amplitude of the point light source may be modulated at frequency Ω.According to our experiment,we study the diffusing equation in theory.And get the results of relationship between the flux and uniform absorption coefficients.This result can directly be used in experiment about image in multiple-scattering media.
