Understanding Infrared Thermography Reading 3

5.2 Exothermic and Endothermic Investigations
An exothermic process is one that releases heat and exhibits a temperature
increase. An endothermic process is one that absorbs heat and exhibits a
temperature decrease. The link between these methods is that the
investigator does not need to apply any thermal stimulation. The relevant
thermal pattern exists in the subject because of another process performed
on (or within) the subject. Applications for thermograpgy in this area are
commonly found in electrical and electronic diagnostics, chemical processes
such as the application of foam-in-place insulation, fire detection, night vision
and surveillance, animal studies, heating and cooling systems and other
areas where thermal energy is released or absorbed.
