Sparse ultrasonic guided wave imaging with compressive sensing and deep learning
Mechanical Systems and Signal Processing(2022)
Abstract
•Sparse UGW imaging with CSDL is proposed and validated in corrosion dataset.•The image quality with only a quarter of the transducers is comparable to that of the full transducers.•The errors of detection signals from are reduced by 3 to 4 orders of magnitude after data reconstruction.
