Abstract
The new model of biotissue as a medium with two kinds of inhomogeneities -- small-scale, representing randomly placed scatterers and absorbers, and large-scale, corresponding to the macroscopic structures -- is proposed. The first and second moments of space-angle intensity distribution of the optical beam propagating in such medium are considered. It is shown that the possibility exists to define parameters of each scale inhomogeneity separately through the moments measurements for conditions often realized in medicine. The results are suitable for development of optical non-invasive diagnostic methods.
