Abstract

Ultrasonic travel time measurements have been made in the time domain by observing the arrival time difference between the selected ultrasonic pulses. In the present work, we carried out a frequency domain analysis of ultrasonic travel time based on the phase difference between the Fourier coefficients of ultrasonic pulses. The purpose of the present analysis is to develop an easier experimental procedure for making accurate ultrasonic velocity measurements. The features of the present frequency domain analysis are to use digitized oscilloscope data of simple pulse reflection measurements, and to incorporate the bond effect correction by constraining the acoustic properties of the bond material. We examined the performance of the present method through test measurements on a fine polished glass plate (bk7 grade), and confirmed an accuracy of ~ 10-4. Its accuracy is critical for utilizing velocity data for constructing the equation of state.
