Pyroelectric Infrared Sensors
During the last decade The Royal Signals and Radar Establishment has been involved in the development of two technologies for infrared detection. The first, using quantum detectors cooled to liquid nitrogen temperatures, has resulted in equipments such as those made by AGA which are now in use in the world’s hospitals. The second, using thermal detectors based on the pyroelectric effect, forms the basis of this paper.
