What is BS EN 61757-2-2 - Fibre optic sensors about?

BS EN 61757 is a series on fibre optic sensors. Fibre optic sensors is a  sensor  that uses  optical fibre  either as the sensing element ("intrinsic sensors") or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). BS EN 61757-2-2 defines detailed specifications for distributed temperature measurement by a fibre optic sensor, also known as fibre optic distributed temperature sensing (DTS). Distributed temperature sensing includes the use of Raman scattering, Brillouin scattering and Rayleigh scattering effects. In addition, Raman scattering and Rayleigh scattering based measurements are performed with a single-ended fibre configuration only. Brillouin scattering based measurements are performed with a single-ended fibre or fibre loop configuration. The te...
