摘　　要：介绍了一种新型的具有双参量测量功能的光纤布喇格光栅传感器。该传感器采用了特殊的结构,安装了两个不同中心波长的光纤布喇格光栅,可以实现两曲面之间狭小间隙的微小位移和温度的同时测量。实验表明,该传感器结构紧凑、体积小,具有良好的重复性和稳定性,位移测量误差不超过±10μm,温度测量误差不超过±2℃。A new fiber Bragg grating sensor which can measure two parameters is introduced. The sensor adopts a special framework for installing two fiber Bragg gratings with different center wavelength. It can simultaneously measure the small displacement and temperature in the clearance between two curved surfaces. The experiments indicate that the sensor is compact in framework, small in volume and excellent in repeatability and stability. The error of diplaeement measurement is not more than ±10μm, and the error of temperature measurement is not more than ± 2 ℃.
