本红外测量装置有一个用于聚集来自人体的红外光束的聚光装置。一引导装置将被监视的空间划分成若干个水平和垂直区域,并将红外光束引导到红外传感器中与光束方向相对应的部分。外壳将聚光装置和引导装置罩住,以减少入射红外光束中的杂散光。 红外传感器可以制成能探测来自一预定区域或来自若干区域的红外辐射。红外光束通过引导装置和外壳进入该测量装
The infrared measuring device has a light condensing device for collecting the infrared light beam from the human body. A guide divides the monitored space into a number of horizontal and vertical regions and directs the infrared beam to a portion of the infrared sensor corresponding to the beam direction. The housing encloses the concentrator and the guide to reduce stray light in the incident infrared beam. Infrared sensors can be made to detect infrared radiation from a predetermined area or from several areas. The infrared beam enters the measuring device through the guide and the housing
