Abstract
An apparatus includes an optical sensor, a lens system, and an optical stop system. The optical sensor includes photocells each of which has a respective photocell active area in a capture plane. The lens system includes lenses each of which is operable to focus light from a respective subfield of a scene into a corresponding focused beam. The optical stop system includes aperture systems each of which confines a corresponding one of the focused beams to a respective illumination area in the capture plane. In a method, light from respective subfields of a scene is focused into corresponding focused beams. Corresponding ones of the focused beams are confined to respective non-overlapping illumination areas in the capture plane. Optical data is generated from light of the focused beams illuminating the illumination areas. Motion measures indicative of movement in relation to the scene are produced from the optical data.
