Averaged PSF cubes simulated with (post-correction) and without (pre-correction) compensating for the NCPAs (see left column, top row). The improvement observed in the “post-correction” case indicates the successful retrieval of the quasi-static phase component associated with NCPAs. The right column demonstrates the corresponding wavefronts and their difference. See Eq. (9) for notation details. Simulated with λ = 1600 nm.
