Abstract
In one embodiment, each of a plurality of optical angle detectors has a plurality of light sensing elements and is positioned at a different location adjacent an optical input area. Each of a plurality of light-control devices is positioned between the optical input area and one of the optical angle detectors, to cause particular rays of light to be mapped to particular light sensing elements of a respective one of the optical angle detectors. The optical angle detectors are positioned to cause each coordinate in the optical input area to be within a field of view of at least two of the optical angle detectors. Other embodiments are also disclosed.
