    • Buried fiber optic intrusion sensor 
      Maier, Eric William (Texas A&M University, 2004-09-30)
      A distributed fiber optic intrusion sensor capable of detecting intruders from the pressure of their weight on the earth's surface was investigated in the laboratory and in field tests. The presence of an intruder above ...
    • Investigations of the Low-Frequency Distributed Acoustic Sensing Response to a Propagating Fracture 
      Leggett, Smith Edward (2022-03-19)
      Low-frequency distributed acoustic sensing has emerged as a significant diagnostic tool for characterizing unconventional completions. The distributed sensor is deployed on a monitor well and provides measurements of ...
    • Magnetostrictive Current Sensor Development Using Fiber Optics 
      Williams, Stephen E. (1991)
      The ability to develop a fiber optic current sensor utilizing the magnetostrictive characteristics of nickel (Ni) has been proven. A Mach-Zehnder interferometer, which had a 2. 5-μm layer of Ni 15-cm long on its sensing ...
