Title: Infrared beam barrier surveillance system - comprises conical reflector collecting radiation from wide angle for IR sensitive diode
Inventor: PENET TRISTAN
IPC: G01V8/10
Filed: 1981-06-01
Abstract: The infra-red detector is intended for use with an infrared beam forming a barrier, the interruption of which indicates the presence of a person or object. The IR sensitive element - a diode (4) -is placed at the apex of a conical reflector (2). The inside surfaces of the reflector are highly polished, and shaped so that any radiation incident on the mouth of the cone reaches the detector after a few reflections. The cone may be folded, so that is mouth opens in a direction at right angles to that in which the detecting element faces. In this case the inside surface of the outside of the elbow (13) is also highly reflecting. The detector is not as sensitive to atmospheric variations as other radiation focussingdetectors.
