| 摘 要： | 设计了一种新型的光纤布拉格光栅(FBG)微位移传感器。基于杠杆原理,通过自由设计不同的力臂长度满足各种测量要求,可以在不损毁光栅的情况下使光栅产生更加显著的应变;其封装不会产生啁啾,可以通过结构的级联实现传感器的复用进行多维多参量的测量。实验结果证明,在微测量范围0.00-0.20 mm内,该微位移传感器的灵敏度达到12.5 nm/mm,较其它梁臂或聚合物封装结构的传感器有很大提高。

| Abstract: | A novel fiber Bragg grating(FBG) micrometric displacement sensor is designed to improve the sensitivity of the current FBG-based sensors.Since this structure is based on the principle of lever,the length of arm of force can be designed arbitrarily to satisfy different requirements of measurement,which results in that the grating can be strained more considerably as long as not being destroyed.Additionally,this packaging structure can avoid chirp,and it is easy to realize sensor-multiplexing to achieve the m... |
