Image Reconstruction Part 2: Advancements in Ptychography through the Alternating Amplitude Flow algorithm

40. Advancements in Ptychography through the Alternating Amplitude Flow algorithm

High-resolution transmission electron microscopy (HRTEM) is a powerful technique for resolving the atomic structure of materials. However, it fails to retain the phase information of the exit wave. To address this limitation, advanced 4D-STEM techniques, such as electron ptychography, have been developed to retrieve phase information and enhance resolution. Conventional electron ptychography...
