双光纤光栅高频加速度传感器的研究
|
摘要
研制了一种新型双光纤光栅加速度传感器,并对该传感器的工作原理和基本特性进行了理论分析,实测表明,这种新型双光纤光栅加速度传感器可在5?2000Hz频率范围内获得稳定的振动信号。这不仅解决了传统悬臂梁FBG加速度传感器难以实现高频振动测量的问题,而且具有温度自补偿、谐振频率高、使用方便等优点,在高频测量中具有广阔的应用前景。
A double Fiber Bragg Gratings(FBG) accelerator sensor was designed and fabricated.The theoretical analysis about working theory and basic characteristic has been carried out.The experimental measurement indicated that the vibration signals with high stability in the frequency range of 5～2 000 Hz were detected with the new double FBG accelerator sensor.The double FBG accelerator sensor not only may overcome the disadvantage of traditional cantilever FBG accelerator sensor that can hardly measure high-frequency vibration signals,but also has some advantages such as temporary self-compensatory,high resonance frequency,handle expediency,and so on.The work indicates that the double FBG accelerator sensor will have broad applications in measuring high-frequency vibration.
