Overview of Fiber Optic Sensors

Fiber optic sensors use optical fibers to detect and measure physical, chemical, biological, or environmental parameters. They can be intrinsic, where the fiber itself senses changes, or extrinsic, where the fiber transmits light to a separate sensing element. Key types include point sensors (e.g., fiber Bragg gratings) and distributed sensors that measure continuously along the fiber length. Applications span structural health monitoring, aerospace, wind energy, high-voltage environments, oil and gas exploration, and industrial automation .
