Research Situation of Ultrasonic Infrared Thermal Wave Technology

Ultrasonic infrared imaging technology is a novel NDE technique, which performs well for material internal defect detection such as metal fatigue crack, composite material impact damage and adhesion and so on. This paper briefly depicted the basic principles and characteristics of ultrasonic IR thermal wave, then summarized research situation at home and abroad, and it finally pointed out deficiencies in the existing research and measures in future development.
