Abstract

Pulse-Echo Thermal Wave IR techniques have been presented at recent SPIE Thermosense Conferences. A brief review is presented along with applications to the detection of adhesion disbonds and corrosion defects in bonded aluminum lap joints. Results for both test panel specimens and aircraft panels are presented. The feasibility of utilizing the technique for rapid, contactless, wide area field inspection of aircraft is discussed. Examples from a recent field test on a B737 aircraft are presented.
