Ultrasonic C-scan imaging of damage in the quefrency domain
, 2023 The ultrasonic pulse-echo method is well-known for the non-destructive inspection of materials. Setting a suitable time gate and searching for ultrasonic echoes, a C-scan image can be obtained in which defects are highlighted. However, such time domain analysis faces several challenges when inspecting multi-layer heterogeneous materials with complex ...
