Paper Abstract

Stone surface monitoring of historical buildings is of interest in the planning of restoration work, both for assessing biodeteriogen growth and for detecting the spectroscopic features of the surface itself. Laser-induced fluorescence (LIF) analysis yields strong signals in the near IR region due to algal depositions while signals through the visible region are useful for the characterization of the stone materials. This paper reports on the first experiments carried out in the framework of a joint project of LTH and IROE-CNR aimed at the fluorescence imaging of historical buildings. We have used a fiber-optical fluorosensor for performing point measurements, and a mobile fluorescence imaging lidar system for remote measurements at a typical distance of 60 m.
