| Abstract: | Solar imaging spectrometer in the extreme ultraviolet band is an important kind of instrument for solar observation. But traditional solar imaging spectrometer cannot observe the Sun in a large field of view simultaneously. Slitless imaging spectrometer allows imaging spectroscopy with high spatial and temporal resolution. Slitless imaging technique is a revolutionary technique for solar research in the extreme ultraviolet band. In this paper, a reconstruction algorithm is studied which has been used in a slitless imaging spectrometer, but it is found that there is a systematic error in the reconstruction result. A new optical design is proposed to solve this problem. By reconstructing the simulated data, the effectiveness of this design is proved. The reconstruction of new design shows better measurement accuracy in Doppler velocity. It will provide more accurate data for space weather studies. |
