| 摘 要： | 提出了一种可用于沥青路面载荷测量的新型高灵敏度光纤布拉格光栅(FBG)压力传感器.传感器采用金属材料和聚合物相结合的封装形式,通过改变聚合物的几何结构实现了高倍数压力增敏效果,并从理论推导了该传感器的光栅中心波长相对偏移量与加载其上压强之间的解析关系.实验结果表明:该传感器的压力监测灵敏度达到2.39×10-8 Pa-...

| Abstract: | A high-sensitivity fiber grating pressure sensor was designed and implemented for load monitoring of asphalt pavement.The sensor used a combination of metal materials and polymer for packaging,and the pressure sensitivity was improved obviously by changing the form of polymer.The analytic formulas between pressure and relative shift of Bragg wavelength of in-fiber Bragg grating were derived.The experimental results show that the pressure sensitivity coefficient is up to 2.39×10-8 Pa-1,which is a... |
