METIS is one of the three first-light instruments planned for the ELT, mainlydedicated to high contrast imaging in the mid-infrared. On the SPHEREhigh-contrast instrument currently installed at the VLT, we observe that one ofthe main contrast limitations is the wind driven halo, due to the limited AOrunning speed with respect to the atmospheric turbulence temporal evolution.From this observation, we extrapolate this signature to the ELT/METISinstrument, which is equipped with a single conjugated adaptive optics systemand with several coronagraphic devices. By making use of an analytic AOsimulator, we compare the amount of wind driven halo observed with SPHERE andwith METIS, under the same turbulence conditions.
