ULTRASONIC TOMOGRAPHY USING SCANNED CONTACT TRANSDUCERS

By 

Abstract

Ultrasonic tomographic images have been obtained from objects of rectangular cross section by scanning spring-loaded transducers across the sample faces. Hemispherical brass caps, placed on each transducer, facilitated sliding along the surface. The complete system was under the control of a microcomputer, resulting in an entirely automatic data collection system. Selected images obtained from this system are presented for metal and rock samples, as well as samples with artificial anomalies
