We have developed a high-resolution, high-speed InSb Focal Plane Array Imager which was built and delivered by Indigo Systems, Inc., of Santa Barbara, CA for use in research and development of thermal wave imaging and nondestructive inspection (NDE) aircraft structures. The design team included Indigo Engineers and faculty from Wayne State. The imager was designed with features intended specifically for use in hangar and field ...
The development of Pulse-Echo Thermal Wave IR techniques is described and reviewed. Applications to NDE of a variety of industrially relevant materials and components is shown. Relationships between experiments and theory are presented. (Author/Modified).
