Adaptive dispersion compensation and ultrasonic imaging for structural health monitoring

Adaptive dispersion compensation and ultrasonic imaging for structural health monitoring

Ultrasonic guided wave imaging methods offer a cost-effective mechanism to perform in situ structural health monitoring (SHM) of large plate-like structures, such as commercial aircraft skins, ship hulls, storage tanks, and civil structures. However, current limits in imaging quality, environmental...
