Light propagation parameters for anisotropically scattering media based on a rigorous solution of the transport equation.
New expressions are presented for light propagation in media for the whole range of absorption and for isotropic as well as for anisotropic scattering with an average cosine of the scattering angle between 0 and 0.9995. The method is based on the rigorous solution of the transport equation for Rayleigh-Gans scattering. The calculated angular intensity distribution was used to determine the absorption parameter K. Expressions for K and the backscattering parameter S are given that can be used to improve existing photon diffusion and two- or four-flux models.
