Book excerpt: Excerpt from Elements of Thermography for Nondestructive Testing Thermography, the process whereby the invisible infrared thermal radiation from an object or a scene is rendered into a visible image, is known mainly for its military surveillance and remote-sensing applications. Nevertheless, thermography has great value also in a variety of non-military applications, and is being exploited in agriculture, geology, environmental control, meteorology, medicine, energy conservation, building, and manufacturing industry. In par ticular, its importance in industry for plant preventive maintenance, process control, quality control, and nondestructive testing has been recognized with the recent establishment of several independent working groups in thermography by different professional societies such as astm, asnt, and spie. This is intended to be a tutorial paper in thermography, espe cially as it relates to nondestructive testing, for program managers and scientists who are unfamiliar with thermal imaging systems and techniques, and who also may not have a background in infrared physics and technology. The material offered herein gives a simple, broad, and mainly qualitative overview which should help the reader to adjudicate the feasibility of applying thermography for his specific purpose. Notwithstanding, thermography is a highly sophis ticated and complex subject, and readers who wish to delve into the theory and the design of thermal imaging systems are referred to the books listed in the bibliography section. The bibliography includes also a listing of periodicals and reports dealing with applications of thermography to nondestructive testing.
