Abstract
Thermal imaging is a technique which has proven quite useful for the nondestructive evaluation of materials, especially locating cracks or disbonds in structures. In thermal imaging, one applies a specified heat flux to the boundary of an object and records the resulting surface temperature as a function of time. From this information one hopes to determine the internal thermal diffusivity of the object, perhaps to locate flaws—cracks, bubbles, corrosion, etc. Some recent work on this subject is detailed in [2], [3], [4] and [7].
This research was carried out while the author was in residence at the Institute for Computer Applications in Science and Engineering (ICASE), NASA Langley Research Center, Hampton, VA, 23681, which is operated under National Aeronautics and Space Administration contracts NAS1-18605 and NAS1-19480.
