Diagnostics Based on Continuous Scanning LDV Measurements and RASTAR Analysis Method

Abstract: This paper presents a technique for rapid diagnostics of structural integrity that exploits spectral sidebands measured by the continuous scanning LDV (CSLDV) measurement method. Structural integrity can be monitored by Operational Deflection Shapes ODSs, which can be quickly measurable at any excitation frequency when a laser continuously scans a vibrating surface. The LDV output time series is an amplitude modulated signal, and its spectral lines are used for recovering polynomial coefficients which build a … Show more

“…The laser Doppler vibrometry (LDV) technique has demonstrated its large potential in terms of spatial resolution [1][2][3][4], moreover, as a non-destructive method, is suitable for ancient and delicate artworks [5,6]. Several authors addressed the diagnostic of artworks through laser-based methods successfully [7][8][9]. Other NDT techniques such as thermography [10], tag-recognition [11] and microwave reflectometry [12] has been also applied to delicate cultural heritage artworks.…”
