ABSTRACT:
Systems and techniques for multiple laser and multiple detector bar code scanning. multiple laser sources generate multiple laser beams directed to a rotating spinner and along optical paths to emerge from a scanner as multiple scan beams. The scan beams trace out a scan pattern within a scan volume. As the multiple scan beams strike an object within the scan volume, reflected light rays are produced representing reflections of the multiple scan beams. As the reflected light rays enter the scanner, they are directed to a collector and focused onto a plurality of detectors so that reflected light rays representing reflections of each scan beam are focused onto a detector associated with the laser source from which the scan beam originates.
