光纤光栅传感技术在工程中的应用

综述了光纤光栅传感器近年来在工程结构健康监测、石油产业、电力行业、岩土工程、航空航天、采矿、爆破、交通及医学等各个领域的应用情况。文章认为,限制光纤光栅传感器产业化和大规模应用的主要因素是缺乏统一的设计理论和制作方法,这使得不同厂家生产的传感器规格存在差异。另外,由于复杂的生产技术和精细的生产过程使传感器生产成本较高,而且能实际应用的光纤光栅传感器的解调产品并不多,且价格很高。根据上述分析,文中对该项技术未来的发展方向提出了展望。

Applications of fiber Bragg grating sensing technology in engineering

This article introduces a systematic review of recent progress in applications of Fiber Bragg Grating （FBG） sensors to Structural Health Monitoring（ SHM）, oil industry, electrical power industry, geotechnical engineering, aerospace , mine, blasting, traffic, medicine, etc. It points out that the lacks of unified theories and standard teehnolgies lead to different product specifications for the Bragg grating sensors from different manufacturers, which limits the industrialization and large scale application of the sensing technology. Further- more, because of their complex and fine manufacturing technologies, the Bragg grating sensors have a higher production cost. Most importantly, the demodulation products are far from enough although many demodulation methods have already been published. On the analysis above, the paper presents its future work.
