Abstract

The transport properties of highly scattering media including biotissues with expressed fibrillar structure are studied by measuring coherent backscattering. Fitting of the experimental data with the coated coherent potential approximation led to evaluation of the transport parameters without a-priori knowledge of the optical properties of scattering particles for strongly scattering dense media. The peculiarities of light diffusion in multiple scattering media characterized by macroscopic anisotropy of scattering properties (such as, the collagen-containing biological tissue with partially oriented fibrillar structure) are introduced. The experimentally obtained ratio of the reduced scattering coefficients in the directions of parallel and perpendicular to the fibers is equal to 0.37 which is in a good agreement with the same value obtained with laser videoreflectometry method.
