  • Specular surface flaw detection
    Patent number: 7362450
    Abstract: An apparatus and a method for detecting low frequency specular surface flaws on coated substrates is disclosed. A method for detecting low frequency specular surface flaws may comprise: impinging visible electromagnetic radiation or light from an electromagnetic radiation source onto the coated substrate at an oblique angle, reflecting the visible electromagnetic radiation off the coated substrate onto a screen material to form a specular surface flaw reflected image, and recording the reflected image off the screen material with a photosensitive device to form a recorded reflected image.
    Type: Grant
    Filed: December 23, 2005
    Date of Patent: April 22, 2008
    Assignee: Xerox Corporation
    Inventors: Kamran Zaman, Dante Pietrantoni, Ken Gottschalk, Stanley Pietrzykowski

  • Fiber optic specular surface flaw detection
    Publication number: 20070146692
    Abstract: An apparatus and a method for detecting low frequency specular surface flaws on coated substrates is disclosed. A method for detecting low frequency specular surface flaws may comprise: impinging visible electromagnetic radiation or light from an electromagnetic radiation source via a plurality of optical fibers onto the coated substrate, reflecting the visible electromagnetic radiation off the coated substrate as a reflected image, and recording the reflected image with a photosensitive device to form a recorded image.
