Abstract : This research has been directed at development and application of non-contact laser, electromagnetic acoustic transducers (EMATs), and air-coupled technology to enhance means for ultrasonic detection of fatigue and corrosion damage in military aircraft structures. The methods which have been investigated include: (1) laser generation/EMAT detection (2) laser generation and detection (3) laser generation/air-coupled detection (4) air-coupled generation and detection.
