Torre, G.; Schwartz, R. A.; Benvenuto, F.; Massone, A. M.; Piana, M. Inverse diffraction for the atmospheric imaging assembly in the Solar Dynamics Observatory. (English) Zbl 1328.85004 Inverse Probl. 31, No. 9, Article ID 095006, 17 p. (2015). Summary: The Atmospheric Imaging Assembly in the Solar Dynamics Observatory provides full Sun images every 12s in each of 7 extreme ultraviolet passbands. However, for a significant amount of these images, saturation affects their most intense core, preventing scientists from a full exploitation of their physical meaning. In this paper we describe a mathematical and automatic procedure for the recovery of information in the primary saturation region based on a correlation/inversion analysis of the diffraction pattern associated to the telescope observations. Further, we suggest an interpolation-based method for determining the image background that allows the recovery of information also in the region of secondary saturation (blooming).
