Abstract

An infrared (IR) sensor for use in a door sensor. The IR sensor may include a plurality of emitters arranged in multiple rows. Each emitter of the plurality of emitters may be configured to emit an emission beam comprising IR light. A plurality of receptors may be arranged in multiple rows. Each receptor of the plurality of receptors may be configured to receive a reception beam comprising the IR light reflected off of a surface. One or more lenses comprising refractive elements may be configured to duplicate and direct one or more of the emission beams and one or more of the reception beams onto the surface to form an IR pattern. The IR pattern may include multiple IR curtains. One or more of the receptors and/or emitters may be deactivated to change a width of the IR pattern and/or number of IR curtains.
