Resumo

A brief retrospective of the development of laboratory X-ray microtomography at the A. V. Shubnikov Institute of Crystallography of the Russian Academy of Sciences (IC RAS) is presented. The main methods and approaches that have increased the informativeness of microtomographic measurements are outlined, such as the use of monochromatic radiation, the application of phase-contrast method, and the method of diffraction tomography (topo-tomography). The designs of the instruments created and operating at IC RAS are described, and some experimental results obtained with them are presented.
