The propagation of laser pulses through the high scattering medium (HSM) consisting of several homogeneous layers, has been theoretically and experimentally investigated. The analytical solution of the radiation transport equation in the «straight back scattering» approximation for multi-layer HSM has been obtained. The experiments with two-layer HSM have been carried out and their correspondence to the theoretical description has been shown. The obtained results may be used for designing of the bio-medical optical tomographs.
