  1. This dissertation is focus on the temperature sensitive mechanism of the brillouin - scattering signal and on the basis of domestic techniques, the methods and approaches of signal detection and processing in distributed brillouin fiber - optical sensor system. a digital multi - point average method ( digital boxcar ) has been proposed based on the characteristics and the sorts of fiber - optical sensors and by analysis the feature of the brillouin - scattering signal, and also comparisons of all sorts of weak - signal detection theory

    論文在全面了解光纖傳感器的分類和特點及分散式光纖傳感器的原理和發展歷程的基礎上,通過分析被檢測的光纖布里淵後向散射信號的特點,研究和比較了微弱信號檢測的各種方法,最終選定了多點數字信號平均(數字boxcar )的處理方案。
