Abstract:
An ultrasonic transceiver comprising:an angle ultrasonic probe arranged on a surface of a test object to transmit to and receive from an interior of the test object at an ultrasonic transmitting direction inclined with respect to the surface of the test object;a scanning mechanism causing a shifting of an ultrasonic transmitting position by the angle ultrasonic probe along the surface of the test object;a display device displaying, on the basis of received output of the angle ultrasonic probe, an image showing the presence or nature of a discontinuity in the test object; anda signal processor performing a signal processing on the received output and supplying a processed received output to the display device;wherein the signal processing shifts an origin position of a time axis as the ultrasonic transmitting position shifts to arrange on a line parallel to a scanning direction axis a plurality of images obtained with a same ultrasonic transmission time, the time axis being an axis representing a time elapse from ultrasonic incidence into the test object and the scanning direction axis being an axis representing a position along a shifting direction of the angle ultrasonic probe.
