An Interactive Simulation and Visualization Tool for Conventional and Aberration-Corrected Transmission Electron Microscopy

Abstract: Contrast transfer function (CTF) is a vital in transmission electron microscopy (TEM). It expresses to what extent amplitudes converted from the phase changes of diffracted waves contribute TEM image, including effects lens aberrations. Simulation very helpful understand application thoroughly. In this work, we develop CTFscope as component Landyne software suite, calculate CTF with temporal and spatial dumping envelopes for conventional extend it various aberrations (up fifth order) aberration-corrected (AC)-TEM. also includes on imaging due objective aperture image drift tutorial purposes. The has user-friendly graphical interface simulation, visualization, saving, loading conditions results. can be used explore instrumental performance information optical aberrations, resolution AC-TEM, teaching courses.
