Explore fiber optic sensors: their working principles, types (intrinsic, extrinsic, hybrid), and diverse applications in mechanical, chemical, and structural health monitoring. Fiber optic current sensors are revolutionizing the way electrical currents are measured, providing high sensitivity, immunity to electromagnetic interference (EMI), and the ability to function in harsh environments. Fibers have many uses in remote sensing. These sensors are capable of measuring a wide range of physical and chemical parameters such as temperature, pressure, vibration, displacement. Fiber units have many variations. The following is a classification example of KEYENCE's fiber units (FU Series). birth of fiber optic sensors. 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.
