New materials and components are often difficult to inspect. Shearography provides full field and non contact deformation and strain measurement in video realtime with very high resolution. This possibility gives it the chance to detect defects inside the component by looking at the strain distribution on the surface of the component during a little mechanical or thermal load. For example a foamed dashboard can be inspected shearographically by putting it into a vacuum chamber and changing the pressure inside the chamber by a slight amount. The enclosed air in voids will cause the expansion of the void and show up in a small deformation of the surface of the dashboard at the void. A shearography system is detecting these deformations and displaying them on a computer monitor. In this paper the technique of shearographic nondestructive inspection and examples of applications in automotive industries, aircraft industry, and terotechnology are given.
