IPC: G01J5/34
Filed: 1993-01-29
Abstract: PURPOSE:To reduce the initial cost and running cost by arranging a plurality of reflectors on the optical path of an infrared ray converging member and a detector. CONSTITUTION:Infrared ray converging member groups LR1-LR3 disposed at parts where the surface and the rear of a detector PE having a light receiving part intersect perpendicularly introduce the converged lights B1-B3 to a reflector M2 through a reflector M1 and the reflected lights enter the detector PE. On the other hand, the light converged by converging member groups LD1-6 disposed within the range of angle of visibility for allowing the directly converged infrared rays to enter the detector PE is reflected on the reflector M2 having sufficiently small area and enters the detector PE with little energy loss. The infrared human body sensor exhibits excellent characteristics over the full angle of visibility of 360 deg.C. Consequently, the initial facility cost, installation cost and running cost for a predetermined space to be managed can be halved.
