Introduction to electron crystallography.
This introduction describes the contributions to this topical issue, and in some cases gives observations on the importance and implications of these articles. Subsequently, there is a discussion of the phase problem and its solution using the unitary equation. This equation, which is true for all known scattering processes, provides a firm theoretical basis for the direct methods of phasing.
