(a) The final pupil function retrieved after 7 iterations. In each iteration, the retrieved pupil function is reversed and discretized into 12×12 segments, then scaled up and applied to the 140-segment deformable mirror. The overall correction pattern added on the deformable mirror is shown in (b). (c) With the correction in (b) applied to the deformable mirror, a majority of the system aberration is eliminated except at the rightmost edge of the pupil plane as shown in this retrieved pupil function. (d) The coefficients of 5–22 zernike components in the retrieved system aberration (a).
