| 摘 要： | 分布式光纤光栅加速度传感技术对微弱振动测量分析及其故障诊断具有重要的实用价值。采用副载波调频、波分复用技术提出了一种分布式光纤布喇格光栅加速度测量系统,并进行了基于双光纤布喇格光栅的加速度传感探头结构的设计。该传感探头具有尺寸小,质量轻,不受电磁干扰等优点,有较高的测量灵敏度和分辨率,而且能自动消除温度噪声和相位噪声的影响。

| Abstract: | The technology of distributed FBG acceleration sensor has become one of the most practical applications in feeble vibration measure and fault diagnosis.A measurement system of vibration acceleration using fiber Bragg grating is presented.The sub-carrier frequency modulation and wavelength division multiplex technology are used in this system.Acceleration sensing probe structure based on dual fiber Bragg gratings is designed.This sensing probe is characterized by small volume,light weight,high sensitivity and resolution,and it has high ability to resist electromagnetic interference.This probe can automatically realize temperature compensation and phase compensation. |
