ABSTRACT

The problem of different skin formations types determining by rapid non-invasive methods requires an integrated approach and today can only be solved on the basis of optical methods. Therefore, numerical simulations experiments of skin formations optical control possibility determining is a demand problem, which allows obtaining backscattering optical radiation characteristics from different kinds of skin formations.
Model experiments based on Monte Carlo method were carried out for different types of human skin. In the simulation experiments backscattered radiation spectra in the visible and NIR are obtained for the skin formations with known optical parameters. For the model backscattering spectra possibility of formation type determining based on the spectrum characteristics is shown.
Model experiments for the case of Raman backscattering from tissue formations are carried out. For different formations types values of radiation intensity corresponding to the Raman shift are defined; possibility of formation type determining at Raman shift detection in backscattered radiation is shown.
