Infrared array sensor system.

摘要

An infrared array sensor system capable of sensing the position and orientation of a human body without using any expensive sensor elements required in conventional infrared array sensors and having functions enabling it to an air conditioner by a relatively simple construction. The infrared array sensor system includes a Fresnel lens for focusing infrared rays, a plurality of guides for guiding the infrared rays focused by the Fresnel lens in predetermined directions, a filter for filtering desired wavelength band ones of the guided infrared rays, a plurality of infrared sensor elements for sensing the filtered infrared rays, the infrared sensor elements corresponding to the directions of the infrared rays guided by the guides, respectively, and a circuit device for processing signals respectively outputted from the infrared sensor elements.
