  • Optical element for a document illuminator
    Patent number: 7586082
    Abstract: An apparatus for recording an image on a sheet comprises a linear array of light sources and an optical element for transmitting light emitted from the light sources. The optical element comprises a light-transmissive member, having an entry surface for disposal near the light sources. The entry surface defines at least one set of prisms. The optical element can further define a DCPC (dielectric compound parabolic concentrator) in cross-section. Collection optics, such as a SELFOC® lens, receives light reflected from the sheet. Each prism of the optical element defines an angle whereby light exiting the optical element is outside the acceptance angle of the collection optics.
    Type: Grant
    Filed: January 24, 2007
    Date of Patent: September 8, 2009
    Assignee: Xerox Corporation

  • Document scanner having replaceable backing and automatic selection of registration parameters
    Patent number: 6744536
    Abstract: A system and method for determining the registration parameters necessary for registration or edge detection processing to enable the flexibility of changing the color of backing to suit a given application. The method includes scanning the backing surface to obtain at least two sets of gray level values; (b) determining an average gray level for each of the two color channels; (c) selecting a registration channel based on the average gray level; (d) determining a gray level deviation for the registration channel; and (e) determining registration parameters based on the average gray level and the gray level deviation of the registration channel.
