Abstract法布里珀罗(F-P)干涉仪是一种多光束干涉仪,具有极高的光谱分辨率,一般用于研究光谱的精细结构。F-P干涉仪的应用受限于自由光谱范围,如果波长超过自由光谱范围,将无法得到光谱的精细结构。基于F-P干涉仪,采用方程组来描述干涉图与光谱曲线之间的关系,并通过奇异值分解方法来解方程组,求出宽谱段范围的光谱曲线,使F-P干涉仪成为一种多光束干涉光谱成像仪,可用于遥感等领域;但奇异值分解法求解光谱曲线,对图像噪声较为敏感,通过仿真结果可以看出,干涉图噪声需控制在0.2%以内才能较好地复原出光谱曲线。
Other AbstractFabry-Perot (F-P) interferometer is a kind of multiple beam interferometer. It has very high spectral resolution, and can be used to research fine structure of the matter. The application of F-P interferometer is limited by the free spectral range. The fine structure of the matter will not be got when the bandwidth of the light surpass the free spectral range. Based on the F-P interferometer, we describe the relationship between the interference pattern and the spectral curve as equation sequence. The equation sequence is solved by the singular value decomposition, and the wide bandwidth spectral curve will be got. By this way F-P interferometer can be used as a spectral imaging instrument. But the algorithm is sensitivity to the noise of the interference pattern. After some simulation work, we find the noise of the interference pattern should be less than 0.2%.
