摘要
分析了光纤光栅传感器的工作原理 ,介绍了成栅技术及应用前景 ,提出了在应用光纤光栅传感技术时解决温度、应力交叉敏感等问题的新方法。研究结果对Bragg光纤传感器在工程技术领域具有一定的应用价值。
The paper reviews the sensing principle, fabrication techniques of fiber Bragg gratings (FBG) and their applications in sensors. Two solutions to temperature and strain cross_sensitivity, which are intrinsic problems of FBG,are described in detail. With these solutions, more accurate information about strain and temperature can be obtained simultaneously. The FBG's application_3s system and the problems met in the project are mentioned. It is demonstrated that the FBE used in sensing technology is superior to other technologies.
