Working principle of chip fiber optic sensor
Fiber optic current sensors work by detecting changes in light as it interacts with a magnetic field created by an electrical current. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. 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"). Due to its small size, low cost and ease of fabrication leading it to replace traditional sensors which were used frequently before th birth of fiber optic sensors.
