摘　　要：光纤型应力传感器具有体积小、质量轻、免电磁干扰、抗腐蚀性 ,灵敏度高等许多独特的优点 ,可在诸如桥梁、楼房、大坝、隧道和精细结构中对所受应力进行长期监控 ,有着巨大的潜在应用前景。结合光纤应力传感的基本原理 ,对目前采用的主要几种光纤应力传感技术进行了详细的介绍。Optical-fiber sensors have many significant advantages, such as small size, lightweight, immunity to electromagnetic interference(EMI), high resistance to corrosive environment and high sensitivity. They are used in bridges, buildings, dams, tunnels and smart structures for long-term monitoring, which have potential application. Combined with the essential principle of the optical fiber strain sensor, we describe the optical-fiber strain sensor technology in detail.
