Abstract

A mathematical model of the interaction of optical radiation with skin tissues is developed taking into account stimulated Raman scattering. Numerical experiments show that the backscattering spectra possess specific features typical of skin pathologies. It is shown that the pathology type can be determined from an analysis of the differential ratios of the Raman scattering intensities at 1271 and 1663 cm−1 to the intensity in the region of 1454 cm−1. It is found that the difference in the differential ratios of the Raman scattering intensities for pathologically changed and normal layers may exceed 40%.
