Estimation of Radiative Properties for Human Skin by Reflection Profile Measurement

An inverse method for estimating radiative properties of scattering and absorbing media has been developed. This method allows us to estimate radiative properties of human skin in vivo in wide range of wavelength. In this method, a target planar medium is non-uniformly irradiated by stripe-like radiation that has passed multi-slits, and the intensity profile of radiation reflected by the medium is measured. The radiative properties, extinction coefficient and albedo, are estimated by an inverse analysis based on the intensity profile of radiation. We applied the present method for human skin, and estimated the extinction coefficient and the albedo of skin in visible range of wavelength.
