What are the current trends in fiber optic sensor technology?

In general, one of the most interesting current trends in fiber optic sensor technology is the miniaturisation of the interrogation units to increase the possibilities of use [ 166 ].

Can fiber optic sensors be used for battery monitoring?

Many sensing methods based on the fiber optic technology have been developed recently for the battery monitoring [ 140 ]. In particular, many fiber optic sensors have been proposed to determine the safe and reliable battery operation by exploiting temperature measurements such as FBGs [ 141, 142, 143] or Rayleigh scattering sensors [ 144] .

What are alternative schemes based on fiber optic sensors?

Alternative schemes based on fiber optic sensors have been proposed using, e.g., FBG [ 161] and Faraday rotating sensors [ 162 ]. The application of fiber optic sensors for current and voltage measurements in the power system is discussed further in “ Power Quality ”.

Can fiber optic sensors be used for lightning detection in overhead power lines?

Fiber optic sensors can be used successfully for lightning detection in overhead power lines, thanks to their immunity to the interference from other electrical signals and operation in harsh environments, providing high accuracy and resolution in terms of both location and severity of the strike.

How does a fiber optic Sagnac interferometer work?

In a fiber optic Sagnac interferometer, a beam of light is split into two paths by a coupler, and each path is then sent around a closed loop in opposite directions. The two paths are then recombined at the coupler, and the resulting interference pattern is detected by a photodetector.
