Abstract

Based on the theory of photon path distribution in semi-infinite homogenous medium, the effect of points with different depth on the detected signal is analyzed, from which a new method of evaluating the spatial reflectance is presented. Furthermore, an approximate theoretical expression of the spatial reflectance in two-layered medium is developed, which agrees with the Monte Carlo simulation results very well.
