摘要 为了将光纤光栅的传感特性应用于结构健康监测和高频应力作用下的材料力学性能测试中,对光纤光栅动态应变传感的测量进行了研究.设计了基于相位载波(PGC)零差法的非平衡Mach-Zender干涉解调系统,并对相位载波解调技术进行了分析.通过对比冲击实验和频谱分析,实验结果证明该检测方法有效可行,可以得到稳定的测量信号,系统在10kHz的频率范围内有良好的频率响应. The aim of this experiment is to apply the fiber Bragg grating sensor to structure health monitoring and testing mechanical characteristics of materials under high frequency stress load, this paper describes a fiber Bragg grating(FBG) sensing system for dynamic strain measurement. An unbalanced MachZehnder (M-Z) interferometric demodulation system is introduced based on the phase generated carrier homodyne technique which is theoretical analysised. By mean of contrast experiment and spectral analysis, the experiment result demonstrates that this system can get steady analog signal and has good frequency response within 10 kHz.
