Over the last several years military applications of infrared photodetectors operating at low temperatures have proliferated. More widespread use of the infrared systems with cooled detectors is limited by a high costs, large size, and inconvenience of operation. At the same time there is no fundamental reason that prevents high performance detection of infrared radiation without cooling. Recently, high performance infrared imagers with uncooled micro-bolometers or other types of thermal detectors have been demonstrated. There are significant efforts on uncooled photon detectors. Sophisticated architecture of the device and high quality materials are necessary to achieve useful performance of uncooled middle MWIR and longwavelength LWIR devices. In this paper we report the use of uncooled infrared photodetectors for military applications such as thermal imagers, smart munitions, laser range finders, threat warning systems, open space communications and others. Various ways to improve performance are described such as optimization of the architecture of the active elements, monolithic integration with immersion microlenses, elimination of traditional processes (radiative and Auger) and others. It is concluded that improved design, materials and processes should reduce or even eliminate the need for cooling of photodetectors in many important military applications of infrared technology.
