摘要
法珀腔光纤传感器是一种适合于智能结构自诊断系统的光纤传感器。在理论分析了法珀腔光纤传感器的基础上,对一种模块化的光纤自诊断系统——光纤智能夹层进行了研究,并对基于光纤法珀腔传感器的光纤智能夹层试件进行了四点弯曲试验。结果表明,光纤智能夹层具有易于制作,使用方便等诸多特点;智能夹层中光纤法珀腔传感器的应变与载荷之间具有良好的线性关系。利用智能夹层中的光纤传感器网络和先进信息处理技术,可以建立结构损伤主动、在线和实时监测系统。
The fiber optic Fabry-Perot sensor is a kind of optic fiber sensor which is fit for the self-diagnosing system of smart constructrue. A kind of modular optic fiber self-diagnosing system, the fiber optic smart layer (FOSL) is studied after optic fiber Fabry-Perot sensor is analysed. Furthermore, FOSL embedded optic fiber Fabry-Perot sensor is performed by using the four-point bending test. The experimental results present that the strain of optic fiber Fabry-Perot sensor is better linear with loading of bending beam. So, the FOSL can be used to monitoring of strain in constructure. And the active and real time monitoring system would be established by fiber optic sensors networks and self-diagnosing modules of FOSL.
