摘要

研究了Sagnac光纤分布式传感器的信号处理。将小波去噪与小波分解相比较，对信号进行频域分析，得到平滑的频谱，在此基础上更准确地找到频谱的零频率。分析有助于更准确地定位扰动。

Signal processing of Sagnac fiber interferometer used as distributed sensor with wavelets

Signal processing is studied for Sagnac fiber distributed sensors. Wavelet denoising and wavelet decomposition are comparatively used to analyze signals in frequency domain to give smoothed frequency spectra, based on which null frequencies of the spectra are found more accurately. The analysis is helpful to more accurately locate the disturbance.
