Measuring isoplanaticity in high-resolution electron microscopy

Abstract:

We recently reported on a new method for the accurate determination of the symmetric aberration coefficients (defocus and twofold astigmatism) from a focal series of high resolution images based on an analysis of the image Fourier transform phases. This can be extended to also cover the antisymmetric aberrations (axial coma and three-fold astigmatism) by recording a combined tilt-focal series where at each beam tilt a short focal series of three images is recorded. In this paper we apply this...
