Thermal imaging systems are, in general, considerably more effective than image intensifiers for surveillance at night, particularly for the detection of personnel, vehicles, boats, etc. Large thermal equipments exist for use on military vehicles and are capable of giving very high performance, usually at high cost and weight. The police have a requirement for a hand-held thermal imager with modest optical performance, but with a compact and lightweight design. This equipment is needed for direct viewing, usually at night, for the detection of missing persons, fugitives etc. in ground and air searches of countryside. A number of existing thermal imaging equipments, including pyroelectric vidicons, and scanned arrays with pyroelectric or cooled detectors have been evaluated. It is concluded that there is no equipment either available now or in the near future that meets the police requirement. A contract has therefore been placed for the development of a thermal viewer and the first of these is expected by September 1977; the specification for this equipment is given.
