Abstract
We investigated the dependence of the diffusion coefficient on the abs orption coefficient by studying the propagation of light emitted by an isotropic source in an infinitely extended medium. Comparisons with b oth experimental and numerical results showed that the diffusion equat ion gives a better description of photon migration when the diffusion coefficient is assumed to be independent of absorption.
