光在分层散射介质中传输行为的蒙特卡罗模拟研究
Monte-Carlo Simulations for Light Propagation in Striated Scattering Medium
摘要
建立了光在分层散射介质中传输行为的蒙特卡罗模型, 计算了皮肤层状结构的光传输特性, 考虑了折射率不匹配带来的影响及不同光束特性(如均匀分布平面光场、 高斯光束、 光纤光束)对传输行为的影响, 分析了分界面处光通量的传输特性, 给出了不同特性光束的生物组织的表面漫射率曲线, 比较了高斯光束和平面光场的卷积结果。
Abstract
Monte-Carlo Simulations for light propagation in striated scattering medium are presented. Considering the influence of refractive index mismatch and different beam profiles (such as uniform flat beam, Gauss beam and fiber beam), the light transport property in the skin striated structure is calculated, and the characteristic of optical flux in the proximity of the interfaces is analysed. The diffusive reflectivity curves of different beams are given and the convolution results of finite-wide flat and Gauss beams are compared.
