Properties of a Polarized Light-Beam Multiply Scattered by a Rayleigh Medium

Multiple scattering of an incoherent beam of polarized light propagating through a random medium is studied using Monte-Carlo simulations. The medium comprises a slab of monodispersive spherical Rayleigh particles. Spatial, angular and path-length distributions of the scattered light are examined in both transmission and backscatter. The change of polarization state is discussed as a function of propagation distance for two initial states. Contrasting linear with circularly polarized light shows the former to be better preserved in all the results obtained. Backscattered light is dominated by single scattering events occurring from the medium closest to the exit plane.
