Due to the unique properties of thermal imagers, their use is not limited by the night-time. In the day-time, they ensure observation through fog, mist and clouds, smoke and camouflage; they are used in medical diagnosis procedures, building and structure security systems, environmental monitoring, and, of course, for military purposes.
All objects emit electromagnetic waves. We see hot objects because they emit light in the visible spectrum. We see cold objects only because light is reflected from them. Our eyes do not perceive their own irradiance. Modern devices allow us to see not only reflected light, but also the light that objects emit.
All thermal-imaging systems normally consist of two units:
- Special optics that ensure focusing thermal radiation on the cooling or non-cooling matrix
- Unit that converts the acquired data to an image visible for the human eye
