  • What signals do fiber optic sensors use

    What signals do fiber optic sensors use

    Fiber optic sensors use optical signals (light) to detect and measure various parameters. 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. In essence, a sensor reacts to a physical, chemical, or biological condition.
