中文摘要：
干涉光谱仪获取的干涉数据是一种中间数据，需要进行光谱反演，常规的方法是采用傅里叶逆变换反演光谱。文章由干涉数据的基本公式入手，推导出干涉数据的混合模型，给出一种基于干涉数据混合模型的光谱反演方法。利用干涉数据对该方法及傅里叶逆变换方法进行计算机仿真，对其光谱反演结果进行对比。由仿真结果可以看出，所提方法反演的光谱精度要优于通用的傅里叶逆变换方法反演的光谱，为干涉数据光谱反演提供新的思路。
英文摘要：
The interferometric data acquired by Fourier transform spectrometer was a betweenness which couldn＇t be used directy. For the successful application of the interferometric data, spectrum recovery processing must be adopted. The conventional method based on inverse Fourier transform was frequently used for spectrum recovery. According to the principle analysis of the interferometric data, the mixing model was induced, and the spectrum recovery method based on the mixing model of the interferometric data was presented. Finally, the computer simulation for these two methods mentioned above was implemented, and the recovered spectra were compared with the standard spectrum. The simulation results indicated that the spectral precision of the new method was better than the conventional method, which provided a new scheme for spectrum recovery.
