摘要
本文介绍了基于F-P原理的光纤应变传感器的基本原理。对碳钢试件作加载试验并进行了应变测量．测得的结果与普通应变电测的测量值相比较，并对系统作了不确定度分析。从测量的数据来看，基于F—P原理的光纤应变传感器具有很好的精度与稳定性，满足混凝土结构安全监测的需求。
The theory of optical fiber strain sensor based on F-P is introduced. The strain of a steel carbide, which is loaded,is measured by strain gauges and F-P strain sensors. The values are compared and the uncertainty of entire system is analysed. Test data shows that F-P strain sensor is stable,accurate and suitable for security monitoring of concrete structure.
