Abstract
In a modified form of electron holography, as originally proposed by Gabor, a specimen illuminated by the focused, convergent beam of a scanning transmission electron microscope is followed by a thin crystal which acts as a periodic array of atomic focusers. Each of the broad diffraction spots of the crystal then contains a magnified image of the specimen with a resolution limit of 0.05 nm or less. The method is illustrated by images of crystal lattice planes and tungsten atoms in the diffraction patterns formed by crystals in the walls of carbon nanoshells.
