It is possible to determine the crystal structure of inorganic compounds to atomic resolution, by combining high resolution electron microscopy (HREM) with crystallographic image proceesing (CIP). An electron micrograph is a magnified, but distorted, image of the object. By quantitative analysis of the image it is possible to determine the distortions and correct for most of them. It is also possible to determine the symmetry of a crystal and even to find the atomic positions with an accuracy of at lcast 0.1 Ångström. The image processing is based on Fourier analysis of the experimental data in the form of a micrograph. The crystallographic symmetry is determined and made maximal use of in restoring a nearly distortion-free image.Il est pos...
