Abstract

The application of optical fiber sensors in hydrogen rich atmospheres and temperatures as high as 300 °C is presented and discussed. Two well known optical fiber sensor technologies are evaluated: (1) distributed temperature sensing, based on Raman scattering, and (2) fiber Bragg gratings. Results show that a new generation of gratings and possibly of fibers that are more hydrogen resistant, both optically and mechanically, are needed.
