The regularities in the changes of the electron wave phases at the exit of a scattering crystal are studied within the framework of the two‐wave dynamical theory for the Laue case with foil thickness and excitation error varying. The dynamical effects are shown to lead to a non‐linear phase change of the transmitted and diffracted waves. The results obtained are used to explain experimental defocused micrographs of a wedge‐shaped crystal with nanometer steps on its surface.
