This paper studies two more complex sources and presents their specific advantages. The first thermoelastic source is a regular line array, whereas the second one is a chirped line array. The surface acoustic waves generated on an aluminum sample by these two thermoelastic sources are detected by an interferometric optical probe, the measurements showing a good agreement with theoretical expectations. Finally, the potentialities of these two sources in NDT applications are described.Show less >
