摘要:
光纤布拉格光栅(FBG)传感器采用普通悬臂梁对非温度物理量进行测量时,存在温度交叉敏感的问题.针对该问题,提出一种基于双厚度等腰三角形的双参量传感器悬臂梁结构,通过理论分析与仿真验证了该结构的可行性,并将单FBG光栅放置于该结构厚度变化交界位置构成双光栅传感.通过光纤传感理论推导和实验系统验证了温度、压力与FBG反射光谱的双波峰共模函数值、双波峰波长差之间的关系.实验结果表明该结构可以实现压力和温度的同时测量,通过双厚度等腰三角形悬臂梁传感结构可有效解决温度交叉敏感问题.
Abstract:
There are temperature cross-sensitivity problems of fiber bragg grating(FBG)sensors for non-temperature measurements using common cantilever beams as the sensitization structure.Therefore,the double-thicknessand isosceles-triangle cantilever beam structure is carried out for solving the problem.It is verified by simulations and theoretical analyses that the structure can serve as a double-intensity cantilever beam.A single FBG grating is placed on the thickness-changing border position for constituting double grating.Based on the fiber sensor theory,the relationship between center wavelength difference of double crest and pressure is given,and the relationship between center wavelength common function value of double crest and temperature is also given.Structure Hence the for pressure and temperature measurements is theoretically proved.It can be proved by the experiment that the temperature is proportional to the modular function value of two crests,but is independent from wavelength difference of two crests.Besides,the pressure is proportional to wavelength difference of two crests,but is independent from modular function value of two crests.The press and temperature are measured by the sensor structure at the same time.In conclusion,these problems of temperature-cross sensitivity are solved by double-thickness and isosceles-triangle cantilever beam sensor structure.
