Abstract

In this paper we present the first results obtained at the ENEA Research Center of Frascati in the diagnosis of stone samples by laser induced fluorescence. The characteristics of the fluorescence spectra (intensity, shape, bands) were both analyzed in coincidence with the laser excitation and up to the fluorescence decay. Two kinds of stones were examined: marble and tuff. In particular, we focused our interest in the different response to the light excitation of the clean and dirty parts of marble. Moreover, a first attempt to detect stone surfaces under water has been carried out. Complementary information has been obtained with measurements of spectral reflectance.
