本文首先提出并设计了一种强度调制的单轴FBG加速度计--直接检测解调系统。进行了不同激励频率下的实验，验证了其良好的机械结构和制造工艺。在此基础上，提出了一种基于单轴FBG加速度计的新型三轴FBG加速度计，并进行了一系列周期性振动试验，以验证其在不同激励频率下的性能。三轴矢量FBG加速度计的响应可以跟上激励频率的增加，在160赫兹内具有良好的信噪比。加速器的合适测量频率范围为0~500赫兹。分析了三个轴之间的横轴响应。这些实验表明，水平轴线对FBG垂直轴振动的影响较小。
Firstly, a single-axis FBG accelerometer with intensity modulation-direct detection interrogation system was put forward and designed in the paper. Experiments with different excitation frequencies were implemented, which demonstrate its good mechanical structure and fabrication technology. Accordingly, a novel tri-axis FBG accelerometer based on the single-axis FBG accelerometer was proposed and a series of periodic vibration tests were finished to prove its performance at different excitation frequencies. The response of the tri-axis vector FBG accelerometer can keep up with the increasing excitation frequency with good signal-to-noise ratio (SNR) within 160 Hz. The suitable measurement frequency range of the accelerator is between 0 and 500 Hz. The cross-axis response among three axes is analyzed. These experiments indicate that horizontal axes have less influence on the vertical axis vibration of FBG.
