空间外差光谱技术(SHS)作为一种新型超光谱分辨率的光谱分析技术近年来得到了快速发展和广泛应用。根据SHS的基本结构和原理，本文对SHS应用系统中能对干涉图产生影响的各种干扰和畸变进行了分析，并针对这些干扰提出了一种SHS干涉图校正方案。实验结果表明，该方案不仅可以对干涉图进行有效校正，而且复原光谱能够良好地反映输入光谱信息，提高SHS的反演精度。

Spatial heterodyne spectroscopy (SHS) has been rapidly developed and widely used in recent years as a new type of super-spectral resolution of spectrum analysis technology. According to the structure and principles of SHS, various kinds of interference and distortion of SHS application system which influence the interferogram are analyzed in this paper and a correction scheme of SHS interferogram for the suppression of the interference is proposed. Experimental results show that the proposed method can correct the interferogram effectively, and make the recovered spectrum reflect the input spectral information well and improve the inversion accuracy of the SHS.
