Abstract
An ultrasonic inspection method in which a pulse signal is output to an ultrasonic sensor to generate and transmit ultrasonic waves, the ultrasonic waves reflected or scattered by an object are received and converted into a waveform signal by the ultrasonic sensor, and the waveform signal is digitized to acquire waveform data, includes: executing modulation processing for modulating a plurality of waveform data acquired in multiple inspections and under the same inspection conditions by a phase modulation method to generate composite waveform data; and executing demodulation processing for demodulating the composite waveform data to generate compressed waveform data.
