The pyroelectric vidicon is an infrared imaging closed circuit television system. The sensor used in the camera tube is a thin pyroelectric crystal which requires no cooling for optimum operation. It is a thermal sensor, as opposed to a photon detector, and can therefore be used over a very broad wavelength region. The system is a passive thermal imager which means that it requires, for its operation, only the electromagnetic radiation which is emitted by all objects which are above absolute zero temperature. In addition, the system incorporates optimized off the shelf video electronic circuitry already developed by the television industry and thus the total system cost can be kept low.
