标准摘要
[中文适用范围]： 该标准适用于基于布里渊散射的分布式光纤传感器，用于测量应变。这种技术广泛应用于结构健康监测、地质工程和工业设备监测等领域。 [外文原描述]： 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.
