| 20090116518 | Multiplexing of optical beams using reversed laser scanning - A high efficiency, low cost, nondispersive optical multiplexing arrangement for optical beams, used a technique denominated “Reverse Laser Scanning.” In the Reverse Laser Scanning operation, different laser beams angularly meet on the rotational axis of a galvanometer-mounted mirror or the like.
