Photon Diffusion in Random Media and Anisotropy of Scattering in the Henyey–Greenstein and Rayleigh–Gans Models

Monte Carlo (MC) numerical simulation is carried out for the intensity of multiply backscattered radiation as a function of the source–receiver distance for the Henyey–Greenstein (HG) and Rayleigh–Gans (RG) anisotropic scattering models. It is found that, in spite of the standard diffusive regime as...

Description
Summary:Monte Carlo (MC) numerical simulation is carried out for the intensity of multiply backscattered radiation as a function of the source–receiver distance for the Henyey–Greenstein (HG) and Rayleigh–Gans (RG) anisotropic scattering models. It is found that, in spite of the standard diffusive regime assumption on the universality of the description of scattering in terms of the extinction coefficient and the transport length, the multiple scattering intensity depends on the form of the phase function and on the degree of anisotropy even for systems with identical extinction coefficients and transport lengths. In this case, the results obtained by the RG phase function are more sensitive to the scattering ansisotropy than those obtained by the HG function.
