2. Fiber-optic current sensor - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_current_sensor

   A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Utilizing a single-ended optical fiber wrapped around the current conductor, [1] FOCS exploits the magneto-optic effect (Faraday effect). [2] The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.

4. Future Fibre Technologies - Wikipedia

   en.wikipedia.org/wiki/Future_Fibre_Technologies

   FFT was established in Melbourne, Australia in 1994 as a research and development company. In 1998, in response to the demand for cost-effective, optical fiber sensors to protect large perimeters, buried pipelines and physical network communication links, FFT developed technology that could pinpoint the location of intrusions over many miles of deployed optical fiber.

5. Distributed acoustic sensing - Wikipedia

   en.wikipedia.org/wiki/Distributed_acoustic_sensing

   In Rayleigh scatter-based distributed fiber optic sensing, a coherent laser pulse is sent along an optic fiber, and scattering sites within the fiber cause the fiber to act as a distributed interferometer with a gauge length approximately equal to the pulse length. The intensity of the reflected light is measured as a function of time after ...

6. Luna Innovations - Wikipedia

7. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   Extrinsic fiber optic sensors use an optical fiber cable, normally a multi-mode one, to transmit modulated light from either a non-fiber optical sensor—or an electronic sensor connected to an optical transmitter. A major benefit of extrinsic sensors is their ability to reach otherwise inaccessible places.

8. Fiber-optical thermometer - Wikipedia

   en.wikipedia.org/wiki/Fiber-optical_thermometer

   Fibre optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, so they can be used for measurement on patients and materials in magnetic resonance scanner (MRI). In strong magnetic fields, there is a small offset in the temperature reading approximately proportional to the strength of the ...
