摘要
设计了光电专业光纤传感单参量测量向双参量升级的简易实验方案,采用宽带掺铒光纤放大器作为光源,光纤双锥马赫-曾德尔干涉仪结合光纤布拉格光栅作为液体折射率与温度双参量传感器,光谱仪测量特征波长变化用于待测量解调.经测试,功能型液体折射率与温度双参量光纤传感系统的折射率传感灵敏度为-34.663nm/RIU,温度传感灵敏度为10pm/℃.
A functional dual-parameter fiber sensing system for simultaneous measurement of liquid refractive-index and temperature was proposed,which was composed of an erbium-doped fiber amplifier as the light source,a dual-parameters sensing unit formed by the combination of a double-taperbased Mach-Zehnder interferometer and a fiber Bragg grating,and an optical spectrum analyzer used for measuring the characteristic wavelengths.The refractive-index and temperature sensitivity of the proposed sensing system were -34.663 nm/RIU and 10 pm/℃ respectively.
