摘要
光纤布拉格光栅(FBG)具有复用能力强、灵敏度高、体积小、耐腐蚀等优点,广泛应用于多种工程监测中。使用193 nm准分子激光器在标准通信单模光纤(康宁,SMF-28)上制备了高反射率FBG阵列,并对其进行了约两个月的长期退火实验研究;设计了一种光纤高温传感系统,可在400 ℃以下对环境的温度进行准分布式测量,测温误差小于0.2 ℃。
Abstract
Fiber Bragg gratings (FBGs) have advantages such as excellent multiplexing capability, high sensitivity, compact structure, and corrosion resistance. Therefore, they have been widely used in various practical engineering applications. In this study, we used a 193-nm excimer laser to fabricate a highly reflective FBG array on a standard communication single-mode fiber (Corning, SMF-28). We performed a long-term annealing experiment for about two months. High-temperature optical fiber sensing systems are designed to achieve quasi-distributed measurement of environment temperature below 400 ℃, with temperature measurement errors of less than 0.2 ℃.
