We describe Sonic Infrared Imaging NDE for materials and structures. In this imaging technique, a short ultrasonic pulse is applied to the structure/material to cause heating of the defects, while an infrared camera images the time evolution of the heating effect to identify the defective areas in the target. The heating effect is astonishing. In this paper, we'll include our study of Sonic IR imaging NDE on aircraft structure specimens, automotive specimens, etc. for metals, composites, ceramics, addressing fatigue cracks, and delaminations/disbonds. Some fundamental issues related to Sonic IR imaging NDE are discussed in this paper as well.
