... wavefields of guided Lamb waves is very time-consuming. To tackle this problem, one possible solution is to acquire the guided Lamb waves in a low-resolution form and then apply a compressive sensing (CS) or a deep learning-based super-resolution approach to that low-resolution form of full wavefields data...

... Abstract Aiming at the problem of image quality reduction caused by sparse array in guided wave detection, an enhanced algorithm based on improved compressive sensing and deep learning is proposed in this paper so as to realize high-quality imaging with a small number of sensors...
