Abstract

Bright- and dark-field images are reconstructed by extracting the intensities of selected spots from a succession of digitalized electron diffraction patterns collected using a transmission electron microscope by scanning the focused beam over the area of interest. The procedure is similar to the generation of the scanning-transmission electron microscopy images. Several examples are shown to illustrate the flexibility and potentiality of such numerical off-line reconstruction.
