Paper Abstract

This paper illustrates the results of an experiment carried out using a fluorescence imaging lidar system with an Optical Parametric Oscillator (OPO) system as the excitation source. Fluorescence spectra of various samples of limestones, sandstones and mortars typically used in the building of historical monuments were investigated exciting at five different wavelengths in the UV region. The spectra were analyzed to produce thematic maps by using multivariate analysis. Besides giving the possibility to identify the optimal excitation wavelength for each specific lithotype or material, the experiment offers prospects for an improved method for the characterization of different materials based on a combined multivariate analysis of fluorescence spectra obtained at different excitation wavelengths.
