Paper Abstract

We study numerically, using the Mie theory, light transmission through a multiply scattering medium composed of a collection of uncorrelated, optically inactive spherical particles. The characteristic length over which a plane wave field is depolarized depends on whether it is initially linearly or circularly polarized and of the size of the particles In a medium containing particles small compared to the wavelength, the characteristic length of depolarization for incident linearly polarized light is found to exceed that for incident circularly polarized light, while the opposite is true in a medium composed of particles large compared to the wavelength. Comparison of numerical results with data from measurements on suspensions of polystyrene latex spheres in water is made. Agreement between these simulations and experiment is good for the range of sizes considered in this paper. We also discuss the relevance of the helicity flip model to the analysis of these data.
