Abstract: Infrared thermography(IRT), as one of the potential non-destructive testing and evaluation (NDT&E) technologies, has gained increasingly attention. In this paper, a comparative research had been made on three kinds of IRT, including eddy current thermography(ECT), optical stimulated thermography(OT)and ultrasonic thermography(UT). The relevant theories, detection systems, applications, data acquisition and processing, and test efficiency and accuracy were compared. Following that, the research focus and potential applications of ECT in defect detection and evaluation were derived out.
