Chromatic and Spherical Aberration Correction with Hexapole and Quadrupole Fields
Shigeyuki Morishita, Hidetaka Sawada, Norihiro Okoshi +4
We report the development of a chromatic and spherical aberration corrector based on combinations of hexapole and quadrupole fields. Thick hexapole fields are used to generate nega…
Electron Fourier ptychography for phase reconstruction
Jingjing Zhao, Chen Huang, Ali Mostaed +10
Phase reconstruction is important in transmission electron microscopy for structural studies. We describe electron Fourier ptychography and its application to phase reconstruction…
LoRePIE: Regularised Extended Ptychographical Iterative Engine for Low-dose and Fast Electron Ptychography
Amirafshar Moshtaghpour, Abner Velazco-Torrejon, Alex W. Robinson +2
The extended Ptychographical Iterative Engine (ePIE) is a widely used phase retrieval algorithm for Electron Ptychography from 4-dimensional (4-D) Scanning Transmission Electron Mi…
