Similarity relations in multiple scattering through turbid media: a Monte Carlo evaluation

Abstract
We discuss the validity and the precision of scaling principles which can be used to transform problems of radiative transfer in media that scatter anisotropically (g does not equal 0, g being the mean cosine of the scattering angle) to equivalent isotropic problems (g equals 0). A Monte Carlo model is used to calculate the reflection (R) and the transmission (T) factors for a collimated incident beam on an anisotropically scattering media, for a wide range of absorption ((kappa) ) and scattering ((sigma) ) coefficients per unit length. The results (R,T) obtained for anisotropic scatterers (g does not equal 0, (kappa) , (sigma) ) are systematically compared to those (R', T') obtained in the case of the equivalent isotropic configuration (g' equals 0, (kappa) ', (sigma) ') as deduced from the similarity relations.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
