Modeling the distribution of optical radiation in diffusely reflecting materials

Diffuse thickness (the sample thickness necessary to bring about complete diffusion of a directed incident light beam) was used to predict the distribution of transmitted radiation in a light scattering medium. The results show that for nonabsorbing wavelengths the shape of the sample is a major factor in determining the distribution of radiation in the medium. As absorption increases the distribution becomes less a function of sample shape. 1.
