The new QTec Scanning Vibrometer is employed to analyze wave propagation resulting from corrosion. At a distance of d = 1.66 m, Lamb wave characteristics were recorded using an AE sensor and compared to a simulated corrosion event signal. The vibrometer's signal correlation enabled wave path reconstruction, ultimately facilitating the localization of the corrosion source by considering reflections and constructive interference effects in the AE sensor time signal.
