A new method for the determination of the wave aberration function for high resolution TEM 1. Measurement of the symmetric aberrations.
A new method for the accurate determination of the symmetric coefficients of the wave aberration function has been developed. The relative defoci and displacements of images in a focus series are determined from an analysis of the phase correlation function between pairs of images, allowing the rest...
