    • Fiber optic interferometric circuit and magnetic field sensor 
      Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1997-07-01)
      A number of optical interferometric sensor configurations are provided. The interferometric sensors include a polarization maintaining optic fiber forming either a loop or linear optical path. Circularly polarized light ...
    • 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 ...
    • Fiber-optic current sensor with improved isolation 
      Blake, James N.; Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2002-03-12)
      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 ...
    • 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 ...
