  • Distributed fiber optic sensing using guided acoustic modes
    Patent number: 11221209
    Abstract: A method for sensing a parameter of an environment surrounding an optical fiber comprises performing a distributed analysis of one or more guided acoustic wave Brillouin scattering (GAWBS) processes taking place therein. This distributed analysis may be performed by spatially mapping a spectral linewidth of a GAWBS coefficient along the optical fiber.

  • Distributed sensing employing stimulated Brillouin scattering in optical fibers
    Patent number: 9163958
    Abstract: Disclosed are methods and devices for distributed sensing of a measurable parameter employing stimulated Brillouin scattering in an optical fiber. A frequency-modulated or phase-modulated light wave is transmitted into the optical fiber. A scattered light wave in the optical fiber is monitored for sensing a measurable parameter. In some embodiments, the calculating step may include calculating a distance of a sensed location along the optical fiber using the monitored time of arrival.
