Abstract
An optical method for identifying locations of objects in a plane, including serially projecting light beams along a detection area, from a plurality of locations along an edge of the detection area, whereby a reflective object inserted into the detection area reflects the projected light beams, directing the reflections of the projected light beams arriving at the edge of the detection area onto a plurality of light detectors, in a manner that maximizes amounts of reflected light arriving at the detectors when the light arrives at a particular angle in relation to the edge, and calculating two-dimensional coordinates of the inserted object in the detection area based on the particular angle and the outputs of the detectors.
