Abstract

An optimized single-end hybrid Rayleigh, Brillouin, and Raman distributed fiber sensing system has been developed for simultaneous measurement of multiple parameters. This system integrates 3-bit pulse coding for the Raman signal and the Brillouin amplification of the Rayleigh-backscattered signal, discriminating strain, temperature, and vibration using a single sensing fiber.

摘要

一种优化的单端混合瑞利、布里渊和拉曼分布式光纤传感系统已被开发出来，用于同时测量多个参数。该系统集成了用于拉曼信号的3位脉冲编码和瑞利背向散射信号的布里渊放大，使用单根传感光纤来区分应变、温度和振动。
