摘要
设计并制作了Fabry-Perot(F-P)干涉型光纤传感器。根据传感器的制作工艺和原理,分析了减小温度系数的方法:设计适当的初始腔长、采用开放腔以及控制光纤与石英套管的粘接方式,都可以有效地控制温度对传感器的影响,以适应传感器在不同场合的应用。对所述方法进行了相应的实验验证,结果表明实验数据与理论分析一致。
The structure of the sensor based on an optical fiber extrinsic Fabry-Perot interferometer which is composed of silica tube and optical fibers is presented. According to fabrication process and operation principle of the sensor, three methods to reduce the temperature coefficient of the sensor are put forward. To design the proper initial cavity length, to hold the cavity opening and to properly glue the fibers and the silica tube are all effective methods. The results show that the experimental data are consistent with theoretical analysis.
