[Modeling and correction of the effect of detector lateral fringe error in the large aperture static imaging spectrometer].
When the large aperture static imaging spectrometry (LASIS) was used in spaceborne remote sensing, the spectrum could not be well recovered from the interferogram with detector lateral fringe error. In order to obtain the more accurate spectrum, the error must be corrected. According to the imaging principle analysis of LASIS, the imaging model with lateral fringe error was given, and the error correction method was presented. Finally, the error correction method was validated with the data acquired by LASIS system. The results indicated that the error was commendably corrected by the method mentioned above, and the accuracy of recovered spectrum was evidently improved.
