Beschreibung
Zusammenfassung:	A sensor determining coordinates of a proximal object, including a one-dimensional array of alternating light emitters and detectors, including a plurality of light emitters projecting light along a detection plane, and a plurality of light detectors detecting reflections of the projected light, by a reflective object in the detection plane, and a plurality of lenses mounted and oriented relative to the emitters and the detectors such that the light detectors receive maximum intensity when light enters a corresponding lens at a first particular angle, whereby for each emitter-detector pair, light emitted by the emitter of that pair passes through one of the lenses and is reflected by the object back through one of the lenses to the detector of that pair when the object is located at one of a set of positions in the detection plane, that position being associated with that emitter-detector pair.
