| 摘 要： | 采用一种简单的传感装置和匹配光纤光栅强度解调的方法，对光纤光栅应变传感进行了理论分析和实验研究，结果表明，检测信号与传感信号的变化频率一致，相位相反，当传感信号的幅度不太大时，它们的变化波形也一致，实验结果与理论分析基本吻合。

| Abstract: | By a simple sensor system and the intensity demodulation method of matched fiber Bragg grating, the fiber Bragg grating strain sensor is studied theoretically and experimentally. The following theoretical conclusions are reached: the frequencies of the detection signal and the sensing signal are the same, their phases are opposite;when the ampltitude of the sensing signal is not too big, their waveforms are the same too. The experimental results are reasonably identical with the theoretical conclusions. |
