Abstract
A defect detection system for thermally imaging a structure that has been energized by sound energy. The system includes a transducer that couples a sound signal into the structure, where the sound signal induces acoustic chaos in the structure that causes defects in the structure to heat up. In one embodiment, the transducer is a broadband transducer. A thermal imaging camera images the structure when it is heated by the sound signal.
