Laser-generated ultrasound in solids

pages 30 - +8p., full text

To better understand ultrasonic wave propagation in thin-wall structures (e.g. glass or composite plates) and to evaluate physical properties of the structure material, new methods for ultrasonic wave generation are necessary. Optical technique using Nd:YAG pulse laser as the wave source is suitable method example. Recorded wave analysis requires application of advanced time-frequency transformation, as is wavelet transformation, by reason of the wave dispersion. In the paper laser ultrasound technique is discussed and some important results of wavelet analysis are shown.
