Experimental laboratory results of closed-loop correction with the iMZ, a 12 × 12 DM, and for the ELT pupil. Left: evolution of the Strehl ratio (measured by the OTF) for 20 iterations of the loop with a gain g = 0.3 and coronagraphic PSFs (right) at first (up) and last iteration (down). Right: wavefront surface measured with the iMZ (asymmetric output) at first (up) and last iterations (down).
