| 摘 要： | 提出了一种基于平面膜片的光纤光栅压强传感器.讨论了该传感器反射谱展宽、峰值波长变化与压强之间的关系.指出将光纤光栅沿径向粘贴在膜片中心附近时,反射谱的峰值波长与压强之间具有良好的线性关系,可以通过检测峰值波长来检测压强.该传感器的压强响应灵敏度系数的实验值为0.3964 nm/MPa,是裸光纤光栅压强灵敏度系数的132.1倍.该传感器的灵敏度系数与压强测量范围可以通过改变膜片的尺寸、材料的弹性模量、泊松比等参量来调节. |

| Abstract: | A kind of plat diaphragm based fiber Bragg grating pressure sensor is proposed. The relations of the spectral broadening, peak wavelength shift and the pressure are analyzed. It is indicates that the peak wavelength of the sensor and the pressure has good linearity when the FBG is attached radially to the diaphragm near the center. The pressure applied on the diaphragm can be measured by the peak wavelength measured. The experimental value of the pressure sensitivity coefficient is 0.3964 nm/MPa. It is 132.1 times of that of the bare FBG. It is also indicated that the pressure sensitivity of the sensor varies with the size and Young′s modulus and Poisson′s ratio of the diaphragm. |
