Fibre Optic Sensors - Part 1-2: Strain measurement - Distributed sensing based on Brillouin scattering

IEC 61757-1-2: 2023 defines detailed specifications for distributed strain measurements with a fibre optic sensor, also known as "fibre optic distributed strain sensing". It is applicable to distributed strain sensing systems (DSS) based on spontaneous or stimulated Brillouin scattering in the optical fibre sensor (strain sensitive element), that is, to sensors capable of measuring absolute strain. This document specifies the most important DSS performance parameters and defines the procedures for their determination.

Capteurs fibroniques - Partie 1-2: Mesure de déformation - Détection répartie basée sur la diffusion de Brillouin

IEC 61757-1-2: 2023 définit des spécifications particulières pour les mesures de déformation réparties avec un capteur fibronique, également appelées "détection de déformation répartie fibronique". Elle s’applique aux systèmes fibroniques répartis de détection de déformation (DSS) basés sur la diffusion de Brillouin spontanée ou stimulée dans le capteur à fibres optiques (élément sensible à la déformation), c’est-à-dire aux capteurs capables de mesurer la déformation absolue. Le présent document spécifie les paramètres de performance DSS les plus importants et définit les procédures pour leur détermination.
