System for optically recognizing and tracking a plurality of objects within a field of vision. Laser (46) produces a coherent beam (48). Beam splitter (24) splits the beam into object (26) and reference (28) beams. Beam expanders (50) and collimators (52) transform the beams (26, 28) into coherent collimated...http://www.google.fr/patents/US4924507?utm_source=gb-gplus-shareBrevet US4924507 - Real-time optical multiple object recognition and tracking system and method
