【Abstract】 From the radiative transfer equation, the analytic results of diffuse reflectance on tissue surface are deduced by diffusion approximation for both the time dependent and the continuous wave source under the condition that a narrow collimated light beam is normally incident upon the surface of tissue. The relation between the optical parameters of tissue and the diffuse reflectance on tissue surface is studied. It supplies a basic principle for noninvasive measure of optical parameters of biological tissue.更多还原
