This paper deals with the optical properties of human tissues that are measured using laser reflectometry method. The result is compared with the phantom and simulation values to get accurate result. The surface Backscattering was determined by laser reflectometry. The tissue equivalent phantom would be prepared with the help of white paraffin wax mixed with various colour pigments in multiple proportions. A familiar Monte Carlo Simulation is used for the analysis of the optical properties of the tissue. The normalized backscattered intensity(NBI) signals from the tissue surface, measured by the output probes after digitization are used to reconstruct the reflectance images of tissues in various layers below the skin surface. From NBI profiles measured at various locations of the tissues on the forearm the corresponding optical parameters, the scattering (ms ) and absorption(ma) coefficient and the anisotropy parameter (g) ,by matching these with profiles as simulated by Monte Carlo procedure are determined.
