置。 Two ultrasonic probes are placed facing each other on the same surface of the test material with a surface defect in between, one for transmitting and receiving, the other for transmitting only, and controlled by the same synchronization signal. In addition, the transmitting-only probe is configured to be driven by a blinking transmitting pulse by switching, and is equipped with a cathode ray tube that displays a received composite waveform of end echoes caused by both transmitting waves. Device.
