Abstract

Analytical model of radiation in highly scattering medium has been developed that describes distribution of scattered photons at arbitrary distance from the directed source. The model operates with minimum number of optical parameters of the medium, such as absorption coefficient and reduced scattering coefficient, the same as the formulas of the diffusion approximation of radiation transport equation. The validity of the model is confirmed by comparing the theoretical data with the results of Monte Carlo simulations.
