| 摘 要： | 提出了一种基于匹配光栅解调技术的加速度检测系统,有效地消除了光源功率变化对信号的影响。在传感器的设计上将传感光栅和参考光栅置于同一环境下,消除了温度对系统的影响,通过试验得到了传感器的频率特性和加速度响应,在实际工程应用中检测到了井下微震信号。

| Abstract: | In this paper,the principle of acceleration measurement by FBG is introduced;matched fiber Bragg gratings(FBG) is adopted as demodulation scheme and a measurement system is proposed as well.The design of putting sensing grating and matching grating together could excludes the influence of temperature drift;the data of frequency character and acceleration response of the sensor are received by the experimental result and real coalmine seismic data is also obtained in project application. |
