Single-stage closed-loop results obtained with the iMZ using 1 second of evolving turbulence, for 0.4 arcsecond seeing, with tip-tilt pre-correction. Asymmetric iMZ output intensity (first row), measures phase command (second row), residual phase maps (third row) and short exposure PSF (fourth row) for a magnitude 7 guide star (N = 108 photons/pixel/frame). The piston has been removed from both phase commands and phase residual maps.
