This report contains an overview of manufacturers of uncooled IR-systems and their performance characteristics, as well as a pilot study of possible applications. Uncooled IR systems have some certain advantages over cooled IR systems: high reliability, low weight, low power requirement, low price. A low price leads to a bigger number of potential buyers and more applications. This in turn leads to a fast sale leading to lower prices. The actors on the market are mainly American companies. Recently, however, several countries in Europe and Asia have developed their own uncooled IR systems. In applications for uncooled IR systems advantage is taken of the small size and the low power requirement. Examples are surveillance, weapon sights and night vision in cars. Uncooled IR systems are well adapted to small mobile systems, which are expected to play a key role in future military operations. Small mobile units can be used for surveillance of e.g. border sectors and may consist of separate IR sensors or combinations with other types of sensors, so-called multi sensors. In future applications uncooled IR sensors may be utilized as parts of sensor networks where radio transmitters are used for wireless communication between the sensors.
