RADIATIVE-TRANSFER IN TURBID MEDIA WITH SPECULAR REFLECTION AT BOUNDARIES

A two-flux model for light propagation in turbid media is proposed bas ed on the differential and integral forms of Pomraning-Eddington appro ximation. The accuracy of the differential form depends on the choice of the weighting function and the boundary conditions, the thickness o f the medium, and the scattering properties of the medium. In the inte gral form, the boundary conditions are imbedded, the range of validity of the approach is extended, and it is also able to deal with anisotr opically scattering inhomogeneous media. Numerical results for partial fluxes and the albedos are calculated and compared with published cal culations.
