Title: Algorithm for angular correction of images in scanning LIF

Abstract: his paper deals with the angular dependence of laser backscattered and fluorescence signals from real target which are scanned in order to determine the actual preservation status of the surface by means of the laser induced fluorescence technique. Different correction algorithms have been proposed and tested on targets with a different fraction lambertian behavior (homogeneous scatterers). The results have been applied in scanning the real surface of a painted icon, for which a RGB image has been reconstructed from the separate fluorescence images collected and processed.
