We present the description of the analysis to compare on a scientific basis the one and two post-focal Deformable Mirrors (DM) configurations of MAORY. We aim to compare the two configurations proposed for the MAORY adaptive optics design, including in the optical path one or two post-focal DMs,ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
