Abstract

Photon migration through diffusive two and three-layered slabs has been studied making use of the diffusion equation, of Monte Carlo simulations and of experiments. We have obtained analytical solutions of the diffusion equation for the diffuse reflectance and transmittance both in the time domain and in the continuous wave domain. The mean pathlength spent by received photons inside each diffusive layer has also been determined by the analytical solutions, by Monte Carlo simulations and by experiments. The results obtained show that the theory proposed is suitable for describing photon migration in diffusive layered media. The analytical solutions have been also used in inversion procedures for retrieving the optical properties of a two-layered slab.
