From: Fly-scan ptychography

The top panel shows the three reconstructed illumination modes with the most powers for diffraction pattern collected at different scan speeds.
The bottom panel shows the power percentage of the recovered modes. With increased scan speed, more illumination power is removed from primary modes and redistributed into other modes. The inset in the bottom-left corner shows the propagation of the reconstructed illumination wave back to pinhole plane. The shape and dimension are consistent with SEM measurement of the pinhole.
