同轴电缆法布里-珀罗传感器的性能测试与分析

摘要

研究不同型号同轴电缆制作的法布里-珀罗(Fabry-Perot,F-P)传感器的感知性能对推广其实际应用具有重要意义.首先阐述了同轴电缆F-P传感器的基本原理,然后选取具有代表性的9种型号同轴电缆制作成F-P传感器,进行了应变和温度感知性能测试,通过对比分析各型号同轴电缆F-P传感器的感知性能指标,得到了一些具有实际工程应用价值的结论.%Research on the sensing properties of Fabry-Perot (F-P) sensors with different types of coaxial cable is of signifi-cance for the promotion and application of coaxial cable F-P sensor. The sensing principle of coaxial cable F-P sensor was de-scribed firstly.Nine types of representative coaxial cables were selected to fabricate the F-P sensors for the strain and temperature performance testing.Through the contrastive analysis of the performance indexes of different coaxial cable F-P sensors,some valu-able conclusions are proposed for practical application.
