Laboratory SCC science images obtained at an exposure of 18 s on the THD2 bench: (a) under the effect of post-AO aberrations only and (b, c, d) under the effect of both post-AO aberrations and static aberrations. b: 0th iteration of the SCC correction loop (starting point). (c) and (d) obtained after five iterations of the SCC correction loop when controlling speckles inside a full dark hole within a 25 λ/D × 25 λ/D region and a half dark hole going from −12.5 λ/D to 12.5 λ/D in one direction and from 2 λ/D to 12.5 λ/D in the other direction.
