ABSTRACT:
A dual aperture optical scanner which employs a single laser beam to produce horizontal and vertical scan patterns. The optical scanner includes a housing having first and second apertures, a laser beam source, a mirrored spinner having a plurality of facets with different elevation angles for reflecting the laser beam in a plurality of directions, and a plurality of pattern mirrors within the housing for reflecting the laser beam from the spinner through the first and second apertures to an article having a bar code label to be scanned. The optical scanner also includes an optical transceiver for passing the laser beam and for collecting reflected light from the scanned article and a photodetector for generating signals representing the intensity of the light reflected from the article.
