Description

Ultrasonic measurements of materials are usually obtained from an electrical conversion of an acoustic signal by a transducer. ln this paper, a conventional (phase sensitive) transducer and a new phase insensitive acoustoelectric converter called an AEC are contrasted. In particular, the AEC is shown to exhibit superior characteristics for many typical experiments and appears to have many applications in the Nondestructive Evaluation (NOE) area.
