The influence of multiple scattering on high resolution electron images of crystalline germanium is analyzed. Identical images are found to recur periodically with thickness and this is discussed in relation to the Pendellosung effect. Identical images also recur periodically with increasing focus (Fourier images). Reverse contrast images (white atoms) are predicted for certain thicknesses. Experimental and computed micrographs of germanium are compared.
