光谱分析法在气体成分监测领域有着广泛的应用，实现小型紧凑高分辨率的光谱测量装置是热门的研究课题。文章创造性的提出了基于光纤法布里-帕罗(F-P)的可调谐滤波器提高吸收光谱分辨率，为构建紧凑高分辨率的光谱仪提供了一种新的方案。基于光纤F-P的可调谐滤波器成功实现了微型光栅光谱仪（分辨率约1nm）对甲烷吸收光谱的测量，对比无光纤F-P可调谐滤波器直接测量的结果，该方法测得的吸收光谱强度至少提高了一个数量级。此研究成果可用于紧凑高分辨率的星载气体检测仪的研制。

Spectrum analysis has a broad prospect of application in gas composition monitoring field. The compact high-resolution gas composition monitoring device has become a subject under intensive investigation. This paper propose a novel solution based on optical fiber Fabry-Perot(F-P) tunable filter in building a compact and high resolution free space optical spectrometer. By using the fiber F-P tunable filter, the absorption spec-trum of CH4 is successfully obtained with a miniature grating spectrometer (resolution of about 1nm). Com-pared with the directly measured results without the optical fiber F-P tunable filter, the intensity of the absorp-tion spectrum has been increased at least an order of magnitude. This research can be used in the development of the compact high-resolution spaceborne gas detector.
