An experimental setup for contactless measurement of the velocity of Rayleigh waves and the surface displacement amplitude
Source abstract
Abstract
An experimental setup is described on which acoustic pulses were recorded from a small surface area. The setup consists of a contactless electromagnetic-acoustic receiver in which the inductor is two thin straight parallel conductors that are positioned a small distance from each other. The velocity of a Rayleigh wave was determined in the 2–10 MHz frequency range. At these frequencies, the length of a surface acoustic wave was varied from 600 to 240 μm and the minimal spacing for measuring the velocity of the Rayleigh wave at a frequency of 10 MHz was 500 μm. A new method for measurement of the time interval between two acoustic pulses is proposed.
