In Vivo Fluorescence Spectroscopy of the Human Skin: Experiments and Models

The results of the experimental investigation of autofluorescence spectra of human skin in vivo caused by the UV radiation of the skin and by the external mechanical pressure applied to the skin are presented. These results are compared with results of Monte Carlo modeling of the autofluorescence of the skin with variable blood content. The proposed simple model of the skin gives the possibility of evaluation of changes of the blood and melanin content within the skin.
