Optical scanner

An optical scanner comprising:

• a substantially horizontal aperture and a substantially vertical aperture;
• an optics engine including
• first and third laser mounts each adapted to mount a laser so that the output beam of the laser is directable through the substantially horizontal aperture;
• second and forth laser mounts each adapted to mount a laser so that the output beam of the laser is directable through the substantially vertical aperture;
• first, second, third, and fourth detector mounts;
• a first laser in the first laser mount for producing a first scanning light beam;
• a second laser in the second laser mount for producing a second scanning light beam;
• a mirrored spinner;
• wherein the first and third laser mounts are located on a first side of the mirrored spinner and the second and fourth laser mounts are located on a second side of the mirrored spinner;
• a first collector between the first and third laser mounts and the mirrored spinner;
• a second collector between the second and fourth laser mounts and the mirrored spinner;
• a first detector in the first detector mount;
• and
• a second detector in the second detector mount;
• first pattern mirrors for receiving the first scanning light beam from the mirrored spinner, for directing the first scanning light beam through the substantially horizontal aperture to produce a first scan pattern, and for directing first light reflected from an item with a barcode label to the mirrored spinner;
• second pattern mirrors for receiving the second scanning light beam from the mirrored spinner, for directing the second scanning light beam through the substantially vertical aperture to produce a second scan pattern, and for directing second light reflected from the item to the mirrored spinner;
• and
• control circuitry for controlling operation of the first and second lasers and the mirrored spinner.
