Figure 6
Example of vignetting. A small (a) and a large (d) test object is propagated to the imaging plane with a magnification of 10. Attenuation has been implemented lens by lens [(b) and (e), 70 propagations] and with an effective vignetting and pupil function [(c) and (f), two propagations]. Simulation details: 2D wavefront, 1200 × 1500 pixels, 5 nm [(a), (b) and (c)] and 400 nm [(d), (e) and (f)] pixel size; see also `Example_Figure_6abc.m' and `Example_Figure_6def.m' of Pedersen (2017BB3).
