Air-coupled ultrasonic tomographic imaging for solids

Research output: Contribution to journalConference articlepeer-review


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.
