Average contrast over the full 10 000 iterations calculated for each 1 λ/D hemispherical bin in both the upper and lower dark holes. The plots show the average contrast per spatial frequency bin in the aberrated open-loop state, post-LDFC correction in closed-loop, and the ideal contrast measurement expected from the reference image. Error bars are given for the closed-loop LDFC contrast measurements denoting the standard deviation of the contrast measured in each 1 λ/D bin for the full 10 000 iterations. This plot clearly shows that running LDFC in closed-loop drives the dark hole contrast back to its initial state as measured in the reference image.
