  • Working principle of metal fiber optic sensors

    Working principle of metal fiber optic sensors

    Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. 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.
