Paper Abstract

In this work the advances of the damage detection and characterization technique based on laser Doppler vibrometer is presented. In particular the algorithms for data processing are analyzed in detail, discussing the advantages and the limitations. Finite element model was employed for the controlled characterization of the procedure. With respect to the previous works, the aim of the present one is to further improve reliability, easiness and readability of the output of the diagnostic procedure and to reduce the amount of the relevant data to be managed. A new algorithm is presented and discussed in detail and numerical and experimental tests are presented.
