Abstract
The coherent diffraction pattern of a non-periodic finite object does not consist of Bragg peaks but is continuously and smoothly varying. Such patterns do not suffer from the well-known phase problem of crystallography. In this case, robust iterative algorithms exist to determine the electron density of the object from the diffraction pattern alone. Continuous diffraction is accessible from ensembles of aligned molecules, including disordered protein crystals. We discuss the application of the concepts of coherent diffractive imaging to such cases and describe the experimental considerations to adequately measure the weak continuous diffraction signals.

Throughout this chapter we will use the indices abc to uniquely distinguish atom a of rigid body b in unit cell c. When it is not needed to report on which body or cell an atom is part of, we just use the index i.
- 2.
Although \({\mathbf {C}}_{ac\,a'c'}\) runs over four subscripts, this is really two dimensional, since any given atom in the crystal is specified by the indices ac (or a′c′) specifying which atom a in the molecule and which unit cell c in the crystal.
