Paper Abstract

The problem of reconstructing a three-dimensional scatterer from measurements of the cylindrical average of the intensity of its Fourier transform is discussed. Reconstruction involves phase retrieval as well as unraveling the effects of cylindrical averaging. The application area considered is x-ray analysis of polymer fibers, and other systems, that consist of collections of rotationally disordered particles. Diffraction from these types of specimens and reconstruction algorithms are described. The particles in these applications often exhibit helical symmetry and the effect of this on reconstruction is described.
