Abstract
A raster scanning system is disclosed which utilizes a laser light source with a plurality of diodes, at least two of which are offset relative to each other. Either one diode or two offset diodes will be selected to scan one scan line. If two offset diodes are selected, two light beams can be generated to scan two partially overlapping paths to form a scan line. By changing the intensity of the two light beams or by selecting two different offset diodes, the scan line can be moved up or down in the sagittal plane. This concept can be used to correct the wobble of a scan line in which case, either one diode or two offset diodes will be selected to scan one scan line in its correct position. Also, the same concept can be used to correct a bow of a scan line in which case, either one diode or two offset diodes 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.
