Common term for fiber optic sensors

Fiber optic sensors do not have a single universal code name; they are typically identified by type, technology, or standard, such as FBG (Fiber Bragg Grating) or interferometric sensors. Fiber optic sensors are devices that use optical fibers either as the sensing element (intrinsic sensors) or to relay signals from a remote sensor to processing electronics (extrinsic sensors) to measure physical quantities like strain, temperature, or pressure (Wikipedia). They are immune to electromagnetic interference, can operate in high-voltage or flammable environments, and are often used where small size or remote sensing is required.

Common designations and types include: FBG (Fiber Bragg Grating) sensors: These are widely used for distributed or point sensing of strain and temperature along the fiber. Interferometric sensors: Use interference patterns of light to detect changes in physical parameters. Extrinsic vs. intrinsic sensors: Extrinsic sensors use the fiber to transmit light to a separate sensing element, while intrinsic sensors have the fiber itself as the sensing medium.

Thru-beam and reflective types: These describe the optical configuration for detection, often used in industrial applications. Standards and identifiers: While there is no single code name, fiber optic sensors are often referenced in technical standards, such as IEEE guidelines, which classify sensors based on their measurand (strain, temperature, pressure) and technology (FBG, Brillouin, interferometric). In practice, engineers and manufacturers refer to sensors by these types or by their application-specific model numbers rather than a universal code name.

In summary, fiber optic sensors are identified by their sensing principle or technology rather than a single code name, with FBG and interferometric sensors being the most common references in technical and industrial contexts.
