中文摘要:

有排水量和温度的同时的察觉到的一个新奇纤维布拉格栅栏(FBG ) 传感器被介绍。FBG inclinedly 在伸臂上被加。FBG 的中点确切与一根矩形的横梁的零紧张层与一致。因为带宽对温度感觉迟钝,垂直排水量能被 FBG 的拓宽的带宽测量,当因为波长移动对垂直排水量感觉迟钝,温度能被中心波长移动测量时。与 0.1 nm 光谱分析器,带宽排水量的敏感和中心波长温度的分辨率是 0.48 nm/mm 和 0.05 nm/ 牦湩敧 ? 楷桴?

英文摘要:

A novel fiber Bragg grating(FBG) sensor with simultaneous sensing of displacement and temperature is presented.The FBG is affixed on the cantilever inclinedly.The midpoint of FBG exactly coincides with the zero strain layer of a rectangular beam.The vertical displacement can be measured by the broadened bandwidth of FBG as the bandwidth is insensitive to temperature,while the temperature can be measured by the center wavelength shift as the wavelength shift is insensitive to vertical displacement.With 0.1 nm spectral resolution of the analyzer,sensitivities of bandwidth-displacement and center wavelength-temperature are 0.48 nm/mm and 0.05 nm/℃,resolutions are 0.2 mm and 2.0 ℃,and sensing ranges of displacement and temperature are up to 8.5 mm and 45℃ respectively.Experimental results match theoretical analyses very well.
