Pigmented skin lesions studied by VIS-NIR diffuse reflectance spectroscopy

Pigmented skin lesions have been studied by optical diffuse reflectance spectroscopy. Our measure system consists of a portable visible near infrared (550-1000 nm) spectrometer, tungsten-halogen lamp and fibre optic probes. The system was tested in steady state conditions. After that, a reproducibility study of normal and pigmented skin spectra was carried out. A small scale study has been conducted in human volunteers with different clinically evaluated lesions. The analysis of the collected spectra is shown.
