摘　　要：大孔径静态干涉成像光谱技术是近年来出现的一种新型干涉成像光谱技术,具有高通量、多通道等优点,然而干涉图与探测器之间存在一定配准误差时,则会对复原光谱产生较大的影响,甚至影响到仪器的最终应用。针对该问题,通过对大孔径静态干涉成像光谱仪成像机理的分析,提出了一种探测器配准误差的标定方法,经验证该方法可以很好地解决探测器的配准误差,最终提高了复原光谱的精度,该研究对大孔径静态干涉成像光谱仪的研制具有重要的指导意义。As a novel type Fourier transform imaging spectrometry, large aperture static imaging spectrometry has come forth in recent years, which has many advantages such as high throughput, multichanneland so on. However, if there are certain registration error on the detector array and interferogram,it will have a greater impact on the restoring spectrum, and even affect the final application of the instrument. To solve this problem, according to the imaging prinple analysis of LASIS, a detector registration error calibration method was given, after verification, this method can well solve the problem of the detector registration error, and the accuracy of recovered spectrum was evidently improved. This study has important guiding significance for the development of large aperture static imaging spectrometer.
