ABSTRACT:
An optical scanner which is configurable to produce a single pattern or a plurality of patterns. The scanner includes an optics engine with first and second laser mounts, first and second detector mounts, a first laser in the first laser mount for producing a first scanning light beam, a mirrored spinner for directing the first scanning light beam, and a first detector in the first detector mount for converting first light reflected from an item with a barcode label into first electrical signals. The scanner further includes pattern mirrors for receiving the first scanning light beam from the mirrored spinner, for producing a first scan pattern from the first scanning light beam for scanning the item, and for directing the first light reflected from the item to the mirrored spinner, and control circuitry for controlling operation of the first laser and the mirrored spinner.
