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.

优化多参数分布式光纤传感器：混合瑞利-布里渊-拉曼系统方法

开发了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，用于同时测量多个参数。该系统集成了拉曼信号的 3 位脉冲编码和瑞利反向散射信号的布里渊放大，使用单个传感光纤来区分应变、温度和振动。
