Abstract

This paper describes the development of a new optical system for accurate measurement of surface wave velocity and attenuation. A mode-locked Q-switch laser generates a Rayleigh wave tone burst which is detected with a two beam interferometer system. The resulting signals are then processed using a simple cross correlation algorithm. Results demonstrating the velocity resolution of the system are presented on both ceramic and metallic samples.
