摘要
布里渊光时域分析(BOTDA)技术是基于光时域反射(OTDR)和受激布里渊散射(SBS)效应的一种重要的分布式光纤传感技术。由于具有多参量传感、精度高、距离长等优势, 该技术特别适用于大型基础设施、石油化工、电力通信网络和海底光缆等长距离、大范围的高危领域的故障定位和健康监测。但传统BOTDA只能用于静态测量, 其应用场合和发展前景受限。综述了目前基于BOTDA的各项动态测量技术, 详细介绍了其测量原理, 讨论了影响其传感速度的基本因素和研究难点, 并展望了未来BOTDA技术的发展前景。
Abstract
Brillouin optical time-domain analysis (BOTDA) is an important distributed optical fiber sensing technology based on optical time domain reflectometry (OTDR) and stimulated Brillouin scattering (SBS) effect. It has many advantages such as multi-parameter sensing, high accuracy, and long sensing distance. Accordingly, it is especially suitable for fault location and health monitoring in high-risk fields such as large infrastructure, petrochemical industry, power communication network and undersea optical fiber cable. The traditional BOTDA is only capable of static measurement, which seriously restricts its application scenarios and development prospects. The dynamic measurement techniques using BOTDA are summarized and the measurement principles are also introduced in detail. The basic factors and research difficulties which affect its sensing speed are discussed, and the future development prospect is forecasted.
