Paper Abstract

We present shearographic imaging of the interaction of AO waves with defects in plates. The images are good when the plates are composite plates, due to some attenuation of the waves which prevents reflections. Those images contain information on the interaction between waves and defects. Nevertheless, this information is very difficult to extract and this extraction need numerical models. Here we show some examples of interaction. It is expected that this images will help to better understand the wave-defect interaction and will help to define and optimize health monitoring systems for carbon-epoxy plates and sandwich plates.
