Abstract:
A raster scanner assembly comprised of:a master clock for generating master clock signals having active edges; an electronic subsystem for producing image data bits that represent a composite image that has both standard image areas and image edges, said electronic subsystem for transmitting said image data bits in substantial synchronization with said active edges; a laser assembly for generating a laser beam in accord with drive signals; an edge sensor, operatively connected to said electronic subsystem, for sensing said image edges; a laser driver producing said drive signals from said image data bits, wherein said drive signals are produced synchronously with said active edges when an image data bit represents a standard image area, and wherein said drive signals are produced earlier than said active edges when an image data bit represents an image edge; and a rotating polygon having a plurality of facets for receiving said generated laser beam from said laser assembly, said rotating polygon for sweeping said generated laser beam in a sweep plane.
