| 摘 要： | 在光纤传感系统中,微弱的信号经常淹没在噪声中。为了很好地实现对光纤传感系统中小信号的检测,必须对光纤传感系统中的噪声进行消噪处理。实验中采用了同步叠加平均消噪法。论文对同步叠加平均消噪方法进行了系统的研究。首先用LabView对叠加平均算法进行了仿真,其次通过对采集卡编程实现了信号采集,并用此方法实现了对带噪信号的消噪处理,最后对实验结果进行了分析。实验结果证明了此方法具有实用价值。

| Abstract: | The small signal was contaminated by strong noise in optical fiber sensor system.To detect the small signal,noise mixed in sensing system must be removed.In the experiment,synchronization overlapping average algorithm was used to suppress noise.In this paper,synchronization overlapping average algorithm was researched systematically.Firstly,the synchronization overlapping average algorithm was simulated with Labview.Secondly,the signal acquisition was realized by the acquisition card and signal process was ... |
