Phase retrieval and aberration correction in the presence of vortices in high-resolution transmission electron microscopy

We discuss phase retrieval and the correction of images for aberrations, in particular defocus and spherical aberration, in high-resolution transmission electron microscopy. Non-interferometric phase retrieval requires at least two intensity measurements in different planes. Vortices in the phase ma...
