音波探傷器。 Ultrasonic pulses are transmitted from the ultrasonic probe to the subject, and the received echo signals are compared with a reference value using a comparison means for each unit time in which the time axis is divided into a plurality of sections. The comparison output data is stored in the storage device in correspondence with the time axis, and each time the ultrasonic pulse is transmitted, the reference value is sequentially changed by the reference value control device, and the comparison output data is stored in the storage device a predetermined number of times. The method is characterized in that the comparison output data is repeatedly obtained in a matrix form using the changing reference value and the time axis, and the comparison output data in the matrix form is further displayed on a matrix-shaped display means. Ultrasonic flaw detector.
