    • Fiber optic current sensor 
      Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2001-02-13)
      A current sensor having an optmized optical fiber coil for sensing the magnetic field of a current of wire passing by or through the coil. The coil is optimally spun such that a particular ratio of the spin rate to the ...
    • 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 Optics apparatus and method for accurate current sensing 
      Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1997-12-09)
      A fiber optics sensor (10) and method for attaining accurate measurement are provided. A polarization maintaining optic fiber (22) forms a linear optical path. An optical element (24) is used to convert linearly polarized ...
    • Fiber optics apparatus and method for accurate current sensing 
      Blake, James N. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1999-11-16)
      The fiber optics sensor includes a polarization maintaining optic fiber forming an optical loop, and a sensing medium coupled to the optic fiber and disposed generally midway in the optical loop. First and second quarter ...
