Ptychographic probe function reconstruction from the Siemens star (a–c) and the diatom (d–f). A plane wave simulation for propagation of the wavefield from a 2.6 µm pinhole aperture is shown in (g, h, i). Amplitude distribution at the position of the pinhole (a, d, g); distribution of the wavefield amplitude downstream of the pinhole (b, e, h); amplitude distribution of the probe amplitude at the position of the sample (c, f, i) [Siemens star (c), and diatom (f)]. The simulated amplitude distribution (i) is shown at the same z position as for (f). Dashed white lines in (b, e) indicate the position of the sample relative to the pinhole at z = 0. White circles in (c, f, i) indicate the pinhole size.
