| 摘 要： | 应变、温度分离是影响光纤布喇格光栅(FBG)传感器实际应用的一个重要问题.该文通过分析FBG应变、温度交叉敏感产生的原因,提出了一种基于双FBGs的用于小应变、小温度变化范围的FBG封装.其中一个FBG只感知温度,另一个FBG既受温度的影响也受应变的影响,通过结果计算就可以分离出应变、温度,而且采用温度增敏后还可以提高温度的测试精度.

| Abstract: | Fiber Bragg Grating(FBG) stain-temperature separation is an important problem which will affect the application of FBG sensor.By virtue of analysis on the reason of FBG stain-temperature cross-sensitive,a FBG sensor package based on double FBGs is described in this paper.One of the FBGs is only affected by temperature and another FBG is affected by both temperature and strain.The stain and temperature can be separated by calculation,and the test accuracy of temperature can be improved after temperature sens... |
