Abstract: A uniform sparse sampling strategy is proposed to improve the acquisition efficiency of the Lamb wavefield of the ROI. The proposed method can recover the guided wavefield of the ROI from a small number of measured signals picked up by the scanning laser Doppler vibrometer using the compressive sensing theory. The experiment is carried out in an aluminum plate with an artificial damage to verify the recovered quality of this method. The experimental results show that the proposed method can reduce the number of measuring points by more than 90% of the traditional Nyquist sampling points in space, and obtain the recovered wavefield with a high coherence coefficient with the original wavefield, and the same time it can realize the positioning and imaging of the structural damage. The research results can greatly improve the efficiency of the damage detection technologies based on the Lamb wavefield analysis.
