Abstract

A compact scanning lidar fluorosensor apparatus has been completed and employed in the diagnosis of wall frescos relevant to the preservation and valorization of European cultural heritage. Preliminary laboratory investigations on natural stones and a painted wood icon were performed before the participation to the Advanced On-Site Laboratory for European Antique Heritage Restoration, held in Constanta (Romania), April 15-30, 2004. The scanning LIF (Laser Induced Fluorescence) prototype was utilized during the campaign to investigate painted walls of a Byzantine crypt. Scanned images at different spectral channels and their suitable combination, showing the effectiveness of the technique to reveal the occurrence of biodegradation produced by different microorganisms, are presented.
