Application of High Resolution Inversion of Ultrasonic Data to the Imaging of Multi-Layered Composite Structures

An Inversion Approach to Ultrasonic Imaging through Reflective Interfaces in Multi-Layered Structures

“…Recently, an efficient inversion algorithm based on the combined application of a layer stripping approach and L2 norm deconvolution has Figure 7. (a) B-scan generated from data following reference subtraction (b) C-scan generated from data following reference subtraction been developed [3,4). This algorithm has been described elsewhere [3) and will not be presented in detail here.…”
