Results of the measurements on the 2D test sample.
(a) Phase image from the ptychographic reconstruction of a 2D test pattern. (b) Resolution estimation of the image in (a) by Fourier shell correlation with an independently measured image recorded at θy = 0° and at θy = 180°, respectively. Because we estimate here the resolution of the individual images rather than their average, we use the 1-bit threshold criterion.
