### Abstract

Several recent papers have dealt with the question of whether large-scale photoelectron diffraction data spanning a significant range in both angle and wavenumber can be analyzed as holograms so as to produce directly three-dimensional images of near-surface atomic structure. Data are thus taken over some volume in the photoelectron wavevector k-space, and then transformed to obtained atomic images. In this work, we review four analysis methods proposed to date for deriving atomic positions directly from photoelectron diffraction data and consider the application of them to theoretical diffraction patterns calculated from various single-scattering model clusters. This permits some general conclusions as to domains of applicability and the optimization of k-space sampling so as to minimize data acquisition time, while still assuring atomic images that are free of coarse k-sampling aberrations. We conclude that holographic imaging of atoms does not require exceedingly large photoelectron diffraction data sets, with a few thousand data points being a suitable minimum, and we also comment on the relative merits of the four different imaging algorithms.
