As a sensing technology based on the principles of optical fiber, fiber optic sensors have gradually become key equipment in many industries due to their advantages, such as high precision, strong anti-interference, and long transmission distances. 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. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. The principle of operation of a fiber sensor is that the transducer modulates some parameter of the optical system (intensity, wavelength. Learn all about the principles, structures, and features of eight sensor types according to their detection principles.
