Abstract
An optical sensor includes light emitters, light detectors detecting an intensity profile of a light beam, focusing lenses refracting light beams onto the light detectors, diverging lenses, each light emitter emits light beams through a respective one of the diverging lenses, and the diverging lens refracts the light beam into multiple divergent light beams that each travel across a detection area and are each directed to a respective pair of the focusing lenses, wherein an intensity profile of each divergent light beam has maximum intensity along the center of the beam, and a processor receiving light profile outputs from the light detectors, and calculating a location of an object in the detection area based on comparing received outputs from two detectors that receive a common one of the divergent light beams partially blocked by the object.
