Time-Domain Topological Energy Imaging Method of Concrete Cavity Defect by Lamb Wave
This paper presents an ultrasonic Lamb wave imaging method based on time-domain topological energy to address artifacts in the results of traditional ultrasound imaging methods. This method is based on topological theory and the calculation of the direct and adjoint sound fields in a defect-free ref...
