Abstract

This paper briefly describes the preliminary results of an experiment that aimed to test a new nondestructive methodology based on the integrated application of Three-Dimensional (3D) terrestrial laser scanning and acoustic techniques in the ultrasonic range (54 kHz) in evaluating the quality of stone materials. Our target is to evaluate the state of conservation of stone materials by correlating ultrasonic longitudinal pulse velocity and frequency spectra with the reflectivity or reflectance of the reflected 3D Laser Scanner (LS) beam pulse transmitted to a part of an investigated surface.
