Description

In recent years, a number of ultrasonic imaging systems for NDE have been developed. 1,2 These systems are mainly composed of expensive high speed electrical circuits, expensive transducers with a number of elements, and signal processing equipment. However, if the processing of signals concerning flaws is based on phase information, the minimum number of transducer elements is only three in the pitch-catch method. This paper deals with a flaw measurement where only three ultrasonic transducers are used at most for localization and sizing of cylindrical flaws.
