  • Illumination for imaging
    Patent number: 6275602
    Abstract: Arrangement for lifting image of checks, with Xenon lamp, Fluorescent lamp or like source of stable-wavelength-output and CCPD Camera means selected to exhibit “close-to-human” spectral response plus a photopic filter, disposed upstream of the Camera and adapted to shift its received image-light spectrum in the direction of that which is optimal for the human-eye.
    Type: Grant
    Filed: June 6, 1994
    Date of Patent: August 14, 2001
    Assignee: Unisys Corporation
    Inventors: David Concannon, John Vala, Gerald Banks

  • Randomizing optical converter for illumination beam and method utilizing same
    Patent number: 4993802
    Abstract: An optical array including a source projecting spectral light onto the input-aperture of a fibre-optic bundle, the bundle's exit-aperture outputting a rectangular beam with fibres "random-laid" and spread-along the exit-aperture to make this rectangular beam's intensity more uniform.
