摘要
主要用实验数据简要叙述光纤Bragg光栅(FBG)的反射谱功率与应力的变化成线性关系,并介绍一种用光功率计测量应力变化的装置,它能够通过测量FBG的反射谱功率较准确地测出应力。
The good relationship between reflection spectrum power of fiber Bragg gratings (FBGs) and stress variation is described briefly utilizing the experimental data. A set-up using optical power meter to measure stress variation is also introduced. It can obtain exactly the stress through measuring the reflection spectrum power of FBGs.
