(Top) Reference image (Iref) of the Siemens star test sample. (Bottom left) Phase profile of the pupil function Φ (colour scale), overlayed with a quiver plot of the retrieved phase gradient ∇Φ vector field (scaled to pixel units). (Bottom right) Four views of the central region of the Siemens star. In the top right is the undistorted view (as outlined in black in the top panel). The remaining three panels show this feature as it appears in different locations on the detector array [after division by W(x)] corresponding to the regions indicated by like-coloured outlines in the left panel.
