Automated system for measuring the phase, velocity, and amplitude of ultrasonic waves in solids

Abstract

An automated system for measuring the velocity, phase, and amplitude of ultrasonic waves in solids in the frequency range 1–20 MHz in CAMAC standard is described. The measurement errors fall within the limits 0.5% for the absolute velocity of acoustic waves, 0.2° for the phase, and 0.5% for the amplitude.
