Abstract

Light-tissue interaction is common in clinical treatments and medical researches, therefore investigation of light path in irradiated tissues is of high importance. In this research, simulations and experimental measurements of the reflected light intensity from one-layered lattices and phantoms are presented. Our results suggest that random walk simulations fit well the photon migration model and enable the extraction of the lattice absorption parameter. The experimental results present a partial fitting to the random walk model: while phantoms presenting different absorption coefficients are distinguished by different reemitted light profiles, the model does not apply an adequate description for the phantom absorption coefficient extraction. This calls for further investigation.
