These sensors rely on the Faraday Effect, which occurs when a magnetic field causes a rotation in the polarization of light passing through an optical fiber. It's a device that converts light rays into electronic signals. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. The fiber optic sensor working principle is that transducer changes some optical fiber system parameters like wavelength, intensity, phase, polarization, etc. The basic working principle is that when the light signal passes through the optical fiber, parameters such as light intensity, wavelength, and phase will be affected by the. 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").

Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor's current-generated magnetic flux, which reflects off a mirror. The light experiences a reciprocal phase shift as the refractive index, and effective path length, is modulated by the presence of a magnetic field, which optically induces circular. The relative to a reference waveform is an optical intensity value corresponding to the.
