Theoretical and experimental multiple scattering results are compared for a two-dimensional geometry. The two-dimensional model predicts the radial distribution of the radiation leaving a semi-infinite isotropically scattering cylindrical medium exposed to colli-mated radiation. The results show that the intensity leaving the media can be expressed as a universal function of the optical radius. The experimental results are obtained using a He–Ne laser beam incident normal to the surface of a tank of distilled water which contains scattering centers (latex paint). The agreement between theory and experiment is good.
