Abstract
A numerical simulation is reported of dynamic multiple (isotropic and anisotropic) scattering of light in a randomly inhomogeneous medium re presenting a suspension of light-scattering Brownian particles. The re sults of a simulation of the temporal autocorrelation function of back scattered light are compared with calculations carried out within the framework of the diffusion approximation for the radiation transport e quation. it is shown that, although the diffusion approximation descri bes incorrectly low-order scattering, it is quite acceptable for deali ng with high-order scattering.
