What is the sensing principle of fiber optic sensors
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. This signal can then be measured by an instrument or interpreted by a user. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Optical fibers provide sensing solutions for many types of applications and environments with high performance.
