Thermal imaging is a non-contact method that registers the emission of heat, i.e. infrared radiation, in a fraction of a second. All bodies emit infrared radiation, even ice. Monitoring the emission of these radiations has found a wide application for monitoring various phenomena in various fields of human activity, such as electronics, mechanical engineering, construction and architecture, but also in medicine. In construction, this method is used to identify "bad" spots, as well as to give a rough estimate of heat loss. Cameras for thermal imaging are similar in appearance to film cameras, but they are specially adapted to "see" that part of the infrared spectrum that is invisible to the human eye, and that is why they are also called infrared cameras.
