Feature-Based Registration for 3D Eddy Current Pulsed Thermography

IEEE Sensors Journal, 2019
Measurement and quantification of defects are the key challenges for eddy current pulsed thermography (ECPT), localization and detection of surface, sub-surface defects, and the quantification of the defects under complex geometry in particular.

Pulsed phased thermography with the wavelet transform

AIP Conference Proceedings, 2000
Pulsed thermography (PT) is a well established approach in nondestructive evaluation of materials: a short thermal perturbation stimulates the specimen of interest and the subsequent surface temperature evolution reveals specimen subsurface structure and thermal properties.

Fuselage disbond inspection procedure using pulsed thermography

AIP Conference Proceedings, 2002
One use of pulsed thermography that has shown promise in aircraft inspection for some time is an inspection for disbonds in metallic structures. The FAA has funded research at Wayne State University in this area and Boeing identified a specific inspection requirement for disbonds on Boeing 747 aircraft. Laboratory and subsequent field testing monitored
