Title: | EXPERIMENTAL APPLICATION OF 3-D TERRESTRIAL LASER SCANNING AND ACOUSTIC TECHNIQUES IN ASSESSING THE QUALITY OF STONES USED IN MONUMENTAL STRUCTURES | Issue Date: | 14-Oct-2007 | Keywords: | Ultrasonic technique 3D terrestrial laser scanner reflectivity spectral analysis |
Subject Classification: | 05. General::05.04. Instrumentation and techniques of general interest::05.04.99. General or miscellaneous | Abstract: | This paper briefly describes the preliminary results of an experimentation aimed to test a new non-destructive methodology based on the integrated application of 3-D 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 building materials by correlating ultrasonic longitudinal pulse velocity and frequency spectra with the reflectivity or reflectance of the reflected 3-D laser scanner beam pulse transmitted to the target of an investigated surface. |
