On scanned single-transducer ultrasonic holography
Abstract
The use of scanned single-transducer ultrasonic holography is being evaluated and applied in a broad range research and development program at Southwest Research Institute in an effort to develop reliable field equipment for the inspection of certain nuclear powerplant components. This paper presents results of laboratory research and development activities which were conducted to gain experience in holographic imaging of typical service-induced flaws, such as fatigue cracks, as well as fabrication flaws, such as slag and lack of fusion. Some discussion on the principles and characteristics of the holographic system is also included.
