  • Variable illumination optical system
    Patent number: 4066351
    Abstract: An optical system in which a screen modulates the light produced thereby. The intensity of the light image is varied as a function of screen position.
    Type: Grant
    Filed: February 20, 1976
    Date of Patent: January 3, 1978
    Assignee: Xerox Corporation
    Inventor: Wayne L. Kidd
  • Optical system alignment apparatus
    Patent number: 4005940
    Abstract: An apparatus in which the alignment of an optical system is displayed, thereby enabling misalignments therein to be corrected. The alignment apparatus, in conjunction with the optical system, generates a narrow sample light image. This sample light image is displayed so as to depict the optical system misalignment. Thereafter the optical system is adjusted and a corrected sample light image produced. The corrected sample light image is once again displayed to insure that the optical system is in alignment.
    Type: Grant
    Filed: February 27, 1975
    Date of Patent: February 1, 1977
    Assignee: Xerox Corporation
    Inventors: Wayne L. Kidd, Stephen C. Corona
  • Illumination system
    Patent number: 3998539
    Abstract: An electrophotographic copying machine having a moving photoconductive member, in which an original document is illuminated by a pair of light sources, which are energized alternately to illuminate the document at a frequency of 240 hertz. This frequency of illumination prevents visible lines in the copy.
    Type: Grant

  • Optical system
    Patent number: 3936173
    Abstract: An optical system in which a screened light pattern and a light image of an original document are projected onto a common region of a light receiving member forming a modulated light image thereon. Collimated light rays are employed in the formation of the screened light pattern.
