| 摘 要： | 提出一种基于空芯光子晶体光纤(HCPCF,hollow core photonic crystalfiber)的Fabry-Perot(HCPCF F-P)干涉应变传感器进行大容量的波分频分复用实验。HCPCFF-P应变传感器的干涉腔长度可达cm数量级,并且温度对应变的交叉影响小。优化制作了HCPCFF-P应变传感器,重点研究了6个不同长度干涉腔应变传感器的波分频分复用实验。实验结果表明,复用系统的应变测量精度可达±20με。

| Abstract: | A fiber-optic Fabry-Perot(F-P) sensor formed by hollow core photonic crystal fiber(HCPCF) is applied in the SFDM/CWDM system.The cavity length of HCPCF F-P can reach several centimeters;in addition the effect of temperature on the measurement of strain is smaller.And we have optimized the manufacture of HCPCF F-P,and realized the multiplexing of six Fabry-Perot strain sensors.The experimental results show that a strain accuracy of ±20 με is achieved,which can meet the requirements of health monitoring for large structures. |
