What are the two categories of fiber optic sensors

Fiber optic sensors are primarily classified into intrinsic and extrinsic types, based on whether the sensing occurs within the fiber itself or externally.Intrinsic Fiber Optic SensorsIntrinsic sensors have the sensing mechanism embedded directly within the optical fiber. The fiber itself acts as the sensing element, and the measurand (physical quantity being measured) directly affects the light traveling through the fiber. Changes in intensity, phase, polarization, or wavelength of the light occur as a result of the environmental parameter, such as temperature, strain, or pressure, acting on the fiber. These sensors are capable of distributed sensing over long distances, making them ideal for structural health monitoring, pipeline surveillance, and other applications requiring continuous measurement along the fiber length .Extrinsic Fiber Optic SensorsExtrinsic sensors use the optical fiber primarily as a light transmission medium. The actual sensing occurs outside the fiber, in an external transducer or "black box" that modulates the light based on the measured quantity. The fiber carries light to and from this external element, which can measure parameters like rotation, vibration, displacement, or temperature in hard-to-reach locations. Extrinsic sensors are advantageous for remote sensing and environments where the fiber cannot directly interact with the measurand .SummaryIntrinsic sensors: Fiber itself is the sensor; light modulation occurs within the fiber; suitable for distributed sensing.Extrinsic sensors: Fiber transmits light to/from an external sensor; modulation occurs outside the fiber; suitable for remote or localized measurements. These two categories form the foundation for most fiber optic sensing systems, with hybrid designs sometimes combining both approaches for specialized applications .
