Title: WIDEBAND ULTRASONIC TIME OF FLIGHT DIFFRACTION COMBINING B-SCANS AND CROSS-SECTIONAL IMAGING

Abstract

Time of Flight Diffraction and Imaging (ToFDI) is a new technique utilizing a sparse array of transducers and signal processing to improve B-Scan output and create a cross-sectional image of a sample. This paper describes preliminary work demonstrating the concept, including; Finite Element Modelling (FEM), basic processing, likely applications. The eventual aim is for fast and automated detection, identification, positioning and sizing for all defects in a sample with known basic characteristics, such as bulk and shear elastic moduli.
