Abstract
A proximity sensor, including a housing, an array of lenses mounted in the housing, an array of alternating light emitters and light detectors mounted in the housing, each detector being positioned along the image plane of a respective one of the lenses so as to receive maximum light intensity when light enters the lens at a particular angle, an activating unit mounted in the housing and connected to the emitters and detectors, synchronously co-activating each emitter with at least one of the detectors, each activated emitter projecting light out of the housing along a detection plane, and a processor receiving outputs from the detectors corresponding to amounts of projected light reflected by an object in the detection plane to the detectors, and calculating a two-dimensional location of the object in the detection plane based on the detector outputs and the particular angle.
