Abstract

An ultrasonic detection assembly for detecting a characteristic in a test object having a cylindrical peripheral surface. The ultrasonic detection assembly includes a phased array probe positioned in proximity to the cylindrical peripheral surface of the test object. The phased array probe includes a plurality of adjacent transducer elements. Each transducer is operatively configured to emit a respective beam into the test object so as to provide a pattern of constructive interference. The ultrasonic detection assembly is structurally configured to provide for cylindrical contact between the phased array probe and the cylindrical peripheral surface of the test object. The ultrasonic detection assembly includes a controller operatively connected to the phased array probe for causing each transducer to emit the respective beam into the test object.
