Schematic diagrams of the optical configuration a and data acquisition for ptychography b. c Typical diffraction patterns and corresponding probe positions used for ptychography (blue). Ptychographic reconstructed amplitude d and phase e of an object function. Instances of amplitude f and phase g of particles picked from d and e, respectively. h Schematic diagram of the optical configuration for TEM data acquisition. i Movie frames collected in TEM mode (left) and translations calculated for individual frames (right). j Motion-corrected image from a movie. k CTF correction by fitting the amplitude spectrum of j. l Picked particles instances from j.
