  • VAD manufacture of optical fiber preforms with improved deposition control
    Patent number: 6923024
    Abstract: The specification describes a VAD method for dynamically controlling the growth rate of both the core soot and the cladding soot in response to separate growth monitors.
    Type: Grant
    Filed: May 9, 2002
    Date of Patent: August 2, 2005
    Assignee: Furukawa Electric North America
    Inventors: Donald P. Jablonowski, Fengqing Wu
  • Manufacture of optical fiber preforms using modified VAD
    Patent number: 6834516
    Abstract: Dynamically controlling the reaction temperature at the tip of a soot preform by controlling the flow of hydrogen gas to the core torch provides a wide latitude of control over the temperature range necessary to produce uniform composition of the preform.
    Type: Grant

  • Laser scanning and multiple detection for video image processing
    Patent number: 4286293
    Abstract: An object (12) is raster scanned with a small, localized beam of laser light (22) and the backscattered radiation therefrom is monitored by a plurality of detectors (44). Each of the detectors (44) monitors a different characteristic of the backscattered radiation and an arithmetic operation is performed on the output of the detectors to provide a single composite video signal with enhanced contrast.
