ABSTRACT:
An ultrasonic technique for remotely inspecting a body is described. A transducer (14), capable of generating and detecting ultrasonic signals, is coupled to the body. An ultrasonic signal (A.sub.o) is launched by the transducer (14) into the body (e.g. 10, 11) and is reflected by any imperfection (e.g. 12) therein. The effects of variations of the transmission coefficient between the transducer and the body are substantially eliminated by intentionally cutting a predetermined calibration notch (22) into the body under test. The analysis of the reflected ultrasonic signals at the notch (22) and at any imperfection (e.g. 12) within the body gives an indication of the quality of the body independently of the transducer/body transmission coefficient.
