Evaluation of internal boundary surface using instantaneous frequency of ultrasonic pulse
An evaluation technique of internal boundary surface using instantaneous frequency of ultrasonic pulse is proposed. The instantaneous frequency represents a variation of the frequency of the ultrasonic pulse waveform from moment to moment. In this paper, a novel technique to acquire precisely the in...
