MULTIPLE LIGHT-SCATTERING IN A 2-DIMENSIONAL MEDIUM WITH LARGE SCATTERERS

A study is presented of the two-dimensional case of light propagation in a turbid medium involving sharply anisotropic one-center scattering in accordance with the Heney-Greenstein law, with strong absorption ( when the photon absorption length is shorter than the transport length ). An exact analytic solution that takes into account fluctuations of the photon paths is obtained within the framework of the small-angle a pproximation for the transfer equation in the case of a light beam nor mally incident upon the plane surface of the medium. The parameters of the radiation distribution (angular spectrum and attenuation coeffici ent) for the deep-propagating mode are analyzed in detail.
