Popis:	Ultrasonic tomography is a powerful tool for identifying defects within an object or structure. Ultrasonic tomography is limited by time consuming transducer coupling. Air‐coupled UPV may eliminate this problem and allow for more rapid data collection. This research aims to integrate recent developments in air‐coupled ultrasonic measurements with the current tomography technology to image inclusions within solids. Air‐coupled ultrasonic signals are collected though large PVC samples. Volumetric and planar inclusions within the samples are identified in the constructed velocity tomographs.
