Multimodal Plane Wave Imaging for Non-destructive Testing

Ultrasonic imaging with high frame rates is of great interest in Non-Destructive Testing (NDT) to perform fast inspections. In this communication, we propose a new fast imaging method for NDT which is derived from the medical Plane Wave Imaging (PWI). The PWI method is applied to immersion-testing configurations (plane or complex water/steel interface between the probe and the image area) and to different imaging modes (imaging with direct or half-skip wave paths) according to the type of defects (point-like or extended crack-types defects).
