A system for the excitation and detection of autofluorescence induced by N2 laser light (337.1 nm, 1 divided by 1.5 mJ/pulse) on biological tissues in vivo is described. Spectra obtained with medium spectral resolution spectrograph were detected with a 512 by 512 CCD array. Spectral measurements performed on patients bearing different cutaneous diseases show that, in the wavelength range 420 - 480 nm, pathological skin tissues fluoresce less than healthy ones and these differences might be useful for diagnostic purposes.

Abstract
A system for the excitation and detection of autofluorescence induced by N2 laser light (337.1 nm, 1 divided by 1.5 mJ/pulse) on biological tissues in vivo is described. Spectra obtained with medium spectral resolution spectrograph were detected with a 512 by 512 CCD array. Spectral measurements performed on patients bearing different cutaneous diseases show that, in the wavelength range 420 - 480 nm, pathological skin tissues fluoresce less than healthy ones and these differences might be useful for diagnostic purposes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
