  • Enhanced radiation resistant fiber optics
    Patent number: 5267343
    Abstract: A process for producing an optical fiber having enhanced radiation resitance is provided, the process including maintaining an optical fiber within a hydrogen-containing atmosphere for sufficient time to yield a hydrogen-permeated optical fiber having an elevated internal hydrogen concentration, and irradiating the hydrogen-permeated optical fiber at a time while the optical fiber has an elevated internal hydrogen concentration with a source of ionizing radiation. The radiation source is typically a cobalt-60 source and the fiber is pre-irradiated with a dose level up to about 1000 kilorads of radiation.
    Type: Grant
    Filed: September 3, 1992
    Date of Patent: November 30, 1993
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Peter B. Lyons, Larry D. Looney
  • System for testing optical fibers
    Patent number: 4212537
    Abstract: A system for measuring a combination of optical transmission properties of fiber optic waveguides. A polarized light pulse probe is injected into one end of the optical fiber. Reflections from discontinuities within the fiber are unpolarized whereas reflections of the probe pulse incident to its injection remain polarized. The polarized reflections are prevented from reaching a light detector whereas reflections from the discontinuities reaches the detector.
