Abstract:
1. An optical imaging system for aligning a light collector to a laser scanline, comprising: an optical assembly for producing a laser beam scanline directed at a scanning platen, the scanning platen including a narrow opening disposed proximate each of its ends in the path of the scanline; first and second photodetectors disposed behind the scanning platen, one at each of the openings, in the path of the scanline, such that the scanning platen is disposed intermediate the optical assembly and the first and second photodetectors; 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 to the scanline.
