Abstract
A method for measuring the diffusion coefficient of homogeneous and layered media, based on multidistance measurements of time-resolved reflectance, i s proposed. The diffusion coefficient is retrieved from the logarithm betwe en two measurements of reflectance at two different distances. The proposed procedure is simpler than others usually employed and also provides a reli able criterion for retrieval of information on the layered structure of a d iffusive medium.
