Paper Abstract

A shearographic measurement system, named ILIAS, is presented which allows the non-contact large area defect detection and structural analysis of composites and other lightweight structures (e.g. in the field of aerospace) with respect to faulty materials and structural defects. Of main interest are defects which are situated below the surface and are not detectable using visual inspection. The use of pulsed illumination additionally allows the vibrational analysis and detection of constructive weak points. In contrast to conventional methods such as ultrasonic, X-ray or eddy current, the ILIAS system allows a fast and large area survey inspection in industrial environments. Applications are presented for composite structures and materials of aircrafts.
