Abstract
We consider the total multiple-scattered light field from a system of Brownian diffusing particles. We assume the correlation function is due to contributions from all the independent single-scattering events leading to the multiple-scattered field. We then assume the relative magnitudes of the various orders of the multiple-scattered light are given by the Poisson distribution. For particles of radius , being the wavelength of light, we arrive at expressions for the depolarization ratio and the polarized and depolarized linewidths as functions of the average number of scattering events , where is the single-particle scattering cross section, is the particle concentration and is a distance related to the scattering volume size. We give experimental data to support our contentions.
