[The impact of blood content in skin tissue on skin spectra].
Based on the analysis of skin structure, and the production mechanism of fluorescence and reflectance spectra, six-layer optical models for skin of different blood content in both upper blood plexus and deep blood plexus were developed, and Monte Carlo simulation was made. The result shows that (1) Both fluorescence and reflectance spectra could reflect the change of blood content in skin tissue; (2) The impact of blood content in upper blood plexus on skin spectra intensity is large, while the impact of blood content in deep blood plexus on skin spectra intensity is small; (3) Fluorescence and reflectance spectra could be used to detect or analyze change of blood content in skin tissue, especially to test the treatment and tune of dermatosis with plexus or blood pathological changes in upper dermis.
