中文摘要：

一个光多部件气体察觉系统基于结合的干涉仪(CI ) 被建议并且试验性地示威了。它能在环境认识到混合气体的集中察觉。当把 CI 与宽带光来源，相结合时， CI 能转变目标气体的吸收光谱到一个结合的排放系列输出光的光谱与目标气体的吸收光谱匹配很好。为不同目标气体的 CI 设计能被代替专心于气体 CI 过滤器的目标的类型完成。当有几种气体，和这个问题时，传统的纤维气体传感器系统要求多重光为察觉采购原料被使用与宽带光来源相结合的 CI 过滤器解决了。试验性的结果证明系统能检测多部件气体的集中，它与 C2H2 和 NH3 被混合。试验性的结果也显示出察觉到线性的好集中。

英文摘要：

An optical multi-component gas detection system based on the conjugated interferometer （CI） is proposed and experimentally demonstrated. It can realize the concentration detection of mixture gas in the environment. The CI can transform the absorption spectrum of the target gases to a conjugated emission spectrum, when combining the CI with the broadband light source, the spectrum of output light matches well with the absorption spectrum of target gases. The CI design for different target gases can be achieved by replacing the kind of target absorbing gas in the CI filter. The traditional fiber gas sensor system requires multiple light sources for detection when there are several kinds of gases, and this problem has been solved by using the CI filter combined with the broadband light source. The experimental results show that the system can detect the concentration of multi-component gases, which are mixed with C2H2 and NH3. Experimental results also show a good concentration sensing linearity.
