Simply put, a fiber-optic sensor, a core component of an optical detection system, transmits and detects signals via optical fibers. 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. Depending on the. An optical fiber sensing system is basically composed of a light source, optical fiber; a sensing element or transducer and a detector (see Fig. In essence, a sensor reacts to a physical, chemical, or biological condition. Unlike traditional electrical sensors (e., periodic monitoring along extensive distances (kilometers), in extreme or hazardous environments, inside.
