Fiber-optic sensor - Wikipedia
A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing.

What is Fiber Optic Sensing? - VIAVI Solutions Inc.
Fiber optic sensing uses the physical properties of light as it travels along a fiber to detect changes in temperature, strain, vibration (acoustics) and other parameters. Fiber optic sensing utilizes the fiber as the sensor to create thousands of continuous sensing points along the fiber.
Advantages of Fiber Optic Sensors • Nonelectrical • Explosion proof • Often do not require contact • Remotable • Small size and light weight • Allow access into normally inaccessible areas • Potentially easy to install (EMI) • Immune to radio frequency interference (RFI) and electromagnetic interference (EMI) • Solid state ...
Fiber optic sensing measures changes in the naturally occurring “backscattering” of light occurring in an optical fiber (or designed in methods of controlled reflection such as Fiber Bragg Gratings). Measurable change is observed when the fiber encounters vibration, strain or …
