  2. In the first place, start with theoretic model of distributed fbg strain - sensing network, sensing principle of fiber bragg grating is analyzed and sensing model created. on the basis of analyzing advantages and disadvantages of several familiar multiplexing and demodulation techniques, a mixture multiplexing method that combines optical frequency domain reflectometry ( ofdr ) and wavelength division multiplexing ( wdm ) is proposed to address fbg sensing array. at the same time, tunable narrow - band light source, which is composed of wide - band light source and tunable optical filter, is adopted to demodulate multiplex signals

    首先,論文從分散式光纖光柵應變傳感網路的理論模型入手,分析了光纖布拉格光柵的傳感機理,建立光纖光柵應變傳感模型;在分析比較了常見幾種復用技術和信號解調技術的優缺點基礎上,提出應用光復用技術和波分復用技術相結合的混合復用方法來解決光纖光柵應變傳感網路的尋址問題,採用由寬帶光源和可調諧光濾波組成的可調諧窄帶光源來解調復用信號,通過理論分析和實驗研究證實了系統方案的可行性。
