COFFEE: NCPA estimation of an introduced phase φ_cal on BOA. Top: for an aberration + φ_cal, recorded coronagraphic image from the bench (left) and computed image using the reconstructed aberration (right) (log. scale, same range for both images). Middle: same images for an aberration − φ_cal introduced and a reconstructed aberration (log. scale, same range for both images). Bottom: calibrated introduced aberration (left) and COFFEE estimated aberration (right).
