Paper Abstract

A new non-contact method for determination of elastic constants with laser ultrasonic waves is presented. A confocal Fabry-Perot interferometer and whole non-contact measure system have been developed for detecting laser- generated ultrasound on rough surfaces. The elastic constants are determined by measured velocities of longitudinal and Rayleigh wave. The experimental results demonstrate that laser ultrasonic techniques are practical and effective.
