Numerical analysis on propagation of light in turbid media using path-length assigned Monte-Carlo simulation

摘要

Using a new algorithm of Monte-Carlo simulation, we simulate the propagation of scattered light under the restricted optical configurations which is corresponds to practical experimental setups of OCTs and DOTs. We demonstrate the path-length distributions of scattered light and the dependence of the distributions of scattering points on the path-length and the scattering order. From numerical results, we discuss the dependence of propagation of scattered light on the scattering order and path-length. This algorithm can speedy and accurately simulate the multiple scattering phenomena under the restricted optical configurations compared with the conventional Monte-Carlo simulation.
