ABSTRACT:
A device for optical scanning of markings, such as barcodes, has at least two transmitters (10, 20) that send light beams (12, 22) at different angles toward a rotating polygonal mirror (30), which deflects the light beams onto the markings being scanned. The light reflected by the markings is deflected by the polygonal mirrors (30) to separate receiver systems, so that the device has and simultaneously uses at least two separate transmitter/receiver channels.
