ABSTRACT:
An optical imaging system and method for the alignment of a light collector with a laser scanline. The optical imaging system includes: an optical assembly for producing a laser beam scanline directed at a scanning platen, the scanning platen including an opening disposed at each of its ends; first and second photodetectors disposed behind the scanning platen, one at each of the openings; a visual indicator coupled to each of the first and second photodetectors to visually indicate detection of the scanline at the openings of the scanning platen; and a light collector assembly for collecting light emitted, reflected or transmitted by a scanned information media, the light collector assembly being pivotable about a centerpoint of the scanning platen and including an adjustment member for pivotably moving the light collector assembly about the centerpoint to align the light collector assembly with the scanline.
