Abstract
Radiance in biological tissue with strong absorption is studied, by solving the steady-state Boltzmann transport equation in P3 approximation for an isotropy point source. We compare the diffusion solution to the total reflectance and the first two terms of the reflectance in P3 approximation respectively, and find that P3 approximation can improve the accuracy, especially in cases of strong absorption. Light radial distribution at the surface is also studied, it is shown that light centralizes in a small area as absorption tends strong. Through many calculations we have drawn a relation between radial width oflight distribution and the absorption coefficient.
