| 摘 要： | 在对光纤光栅强度解调方法研究的基础上，利用FastFET放大器AD8065设计了高速光电转换电路，并基于边缘滤波强度解调原理构建了光纤光栅振动检测系统。该系统具有成本低、解调速度快等特点。在实验中，引入使用美国国家仪器（NI）有限公司的电子电路仿真软件Multisim的仿真实验与构建的光纤光栅振动检测系统进行对比。实验结果表明，光纤光栅振动检测系统具有良好的幅频响应，频率响应范围可达5 Hz~1000 Hz，为光纤光栅振动检测提供了一种新的可靠手段。

| Abstract: | On the basis of the research on intensity demodulation method of Fiber Bragg Grating,High speed photo?electric conversion circuit was designed with FastFET amplifier AD8065 and a Fiber Bragg Grating vibration detec?tion system based on edge filter demodulation is established. The system has advantages of low cost,fast response and so on. In the experiments,simulation experiments results from National Instruments(NI)Ltd Electronic Multi?sim circuit simulation software are used to compare with the results of the fiber grating vibration demodulation sys?tem. The results show that The Fiber Bragg Grating vibration detection system has good amplitude frequency re?sponse,and its frequency response range is 5 Hz~1 000 Hz,which provides a new reliable method for Fiber Bragg Grating vibration detection. |
