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。
Large-aperture static interference imaging spectroscopy is a new type of interferometric imaging spectroscopy in recent years. It has the advantages of high throughput, multi-channel, etc. However, when there is a certain registration error between the interferogram and the detector, Have a greater impact, and even affect the final application of the instrument. Aimed at this problem, a calibration method of detector registration error is proposed by analyzing the imaging mechanism of large aperture static interference imaging spectrometer. The method is proved to be a good solution to the detector registration error, Spectral accuracy, the study of large aperture static interference imaging spectrometer has important guiding significance.
