Fiber Optic Sensors: Types, Working Principle
Explore fiber optic sensors: their working principles, types (intrinsic, extrinsic, hybrid), and diverse applications in mechanical, chemical, and structural health monitoring.
Home / What is the light transmission principle of fiber optic sensors
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. The optical fiber consists of the core and the cladding, which have different refractive indexes. 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").
