Reconstruction Algorithm for Atomic Resolution Holography

Abstract

Atomic resolution holography, for example photoelectron holography and x-ray fluorescence holography, is a type of atomic structural analysis. These measurement methods can visualize the three-dimensional atomic structure around the target atomic site. These methods can also measure the atomic structure around an impurity in the crystal or an adsorbate on the crystal. The atomic image is obtained from the measured hologram using a reconstruction calculation. We developed scattering pattern extraction algorithm with maximum entropy method (SPEA-MEM) for atomic image reconstruction. In this paper, we describe the theory of the SPEA-MEM.
