    • Fiber optic interferometric sensor and method by adding controlled amounts of circular birefringence in the sensing fiber 
      Blake, James N.; Short, Shayne X. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2000-02-08)
      A fiber optic interferometric sensor (10, 70) includes a sensing fiber (32, 92) which forms a closed optical path around a current-carrying conductor (44, 94). The sensing fiber (32, 92) has a predetermined number of twists ...
    • Magnetic field integrated fiber optic sensor with improved sensitivity 
      Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2001-10-23)
      A current sensor coil design for reducing or eliminating long undulations of magnetic sensitivity. Such reduction or elimination improves isolation of the current sensor such that proximate currents and accompanying effects ...
    • Signal conditioning unit for fiber optic sensors 
      Taylor, Henry F.; Sadkowski, Roberto; Lee, Chung E. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1996-09-17)
      Apparatus and method (10, 50) for determining the value of a measurand measured by a fiber optic interferometer sensor (24, 72, 110) is provided. The apparatus includes a light source (16, 58, 102) emitting a light having ...
