    Abstract: A raster scanning system (30) is disclosed which utilizes a laser light source (32) with a plurality of diodes (34,36), at least two of which are offset relative to each other. Either one diode or two offset diodes (34,36) will be selected to scan one scan line. If two offset diodes (34,36) are selected, two light beams (38,40) can be generated to scan two partially overlapping paths (spots Sa, Sb) to form a scan line (spot Sr; Fig. 3). By changing the intensity of the two light beams (38,40) or by selecting two different offset diodes (34,36), the scan line (spot Sr; Fig. 3) can be moved up or down in the sagittal plane (50). This concept can be used to correct the wobble of a scan line (spot Sr; Fig. 3) in which case, either one diode or two offset diodes (34,36) will be selected to scan one scan line (spot Sr; Fig. 3) in its correct position. Also, the same concept can be used to correct a bow of a scan line (spot Sr; Fig. 3) in which case, either one diode or two offset diodes (34,36) will be selected for each pixel to correct the bow in accordance with a pre-defined correction data for that pixel which is stored in a memory.

Either one diode or two offset diodes (34,36) will be selected to scan one scan line. If two offset diodes (34,36) are selected, two light beams (38,40) can be generated to scan two partially overlapping paths (spots S a , S b ) to form a scan line (spot S r ; Fig. 3). By changing the intensity of the two light beams (38,40) or by selecting two different offset diodes (34,36), the scan line (spot S r ; Fig. 3) can be moved up or down in the sagittal plane (50). This concept can be used to correct the wobble of a scan line (spot S r ; Fig. 3) in which case, either one diode or two offset diodes (34,36) will be selected to scan one scan line (spot S r ; Fig. 3) in its correct position. Also, the same concept can be used to correct a bow of a scan line (spot S r ; Fig. 3) in which case, either one diode or two offset diodes (34,36) will be selected for each pixel to correct the bow in accordance with a pre-defined correction data for that pixel which is stored in a memory.

    Abstract: A multiple beam raster output scanning (ROS) system has a reduced number of optical elements with the sagittal portions of the beams requiring only a spherical diode lens and a wobble correction mirror for each beam. The tangential portions of the beams require only the spherical diode lens and a shared common tangential lens and a shared common two element f-theta scan lens. Fold mirrors are used to provide a compact raster output scanning system.

    Abstract: A heating element adjusts the curvature of a cylindrical wobble correction mirror to compensate and correct the scan line bow for an optical scanner. A current applied through the heating element along one side of the mirror will cause the mirror to bend vertically for a horizontal beam to adjust the scan line bow for a single beam and approximately equalize the scan line bow for multiple beams.

    Abstract: A printing system (40) in which an array of VCSELs as a light bar printhead (42) directly sends an array of light beams (44) onto a photoreceptor (46) without using an imaging optical element. The VCSELs are selected which have slowly diverging light beams. The photoreceptor is placed at a predetermined distance from the VCSELs where the light beam has a width equal to a desired spot corresponding to a given printing resolution.
