摘要
本文介绍一种适于埋入混凝土结构内的螺旋线微弯增敏光纤传感,描述其工作原理,并给出与光时域变换技术结合运用的实验结果。
This paper reports a spiral sensitized microbending optical fiber sensor witch is applicable to strain monitoring of concrete structure. The principle and the structure are described. Combined with Optical Time Domain Reflectometer (OTDR),this kind of microberiding sensor can be used for quasi-distributed strain measurement of the concrete structure.
