Infrared thermal imaging

A thermal imaging camera consists of five components: an optic system, detector, amplifier, signal processing, and display. Fire-service specific thermal imaging cameras incorporate these components in a heat-resistant, ruggedized, and waterproof housing. These parts work together to render infrared radiation, such as that given off by warm objects or flames, into a visible light representation in real time. The camera display shows infrared output differentials, so two objects with the same temperature will appear to be the same "color". Many thermal imaging cameras use grayscale to represent normal temperature objects, but highlight dangerously hot surfaces in different colors. Cameras may be handheld or helmet-mounted. A handheld camera requires one hand to position and operate, leaving only one free hand for other tasks, but can be easily transferred between firefighters. The majority of thermal imaging cameras in use in the fire service are handheld models. [Thermal imaging camera (firefighting). Wikipedia]
