    • Intrinsic Fabry-Perot optical fiber sensors and their multiplexing 

      Virginia Tech Intellectual Properties, Inc.; Wang, Anbo (United States Patent and Trademark Office, 2007-12-11)
      An intrinsic Fabry-Perot optical sensor includes a thin film sandwiched between two fiber ends. When light is launched into the fiber, two reflections are generated at the two fiber/thin film interfaces due to a difference ...
    • Optical fiber sensors based on pressure-induced temporal periodic variations in refractive index 

      Virginia Tech Intellectual Properties, Inc.; Wang, Anbo (United States Patent and Trademark Office, 2006-11-21)
      A optical fiber sensor for measuring temperature and/or pressure employs temporally created long period gratings. The gratings may be produced by a periodic change in the refractive index of the fiber along the fiber ...
