A “scattering pattern matrix” method is proposed here to
overcome the difficulties presented by photoelectron holography,
such as forward-scattering and multi-energy problems. This method
makes it possible to reconstruct a three-dimensional atomic
arrangement from a single-energy hologram. We have utilized the
“scattering pattern matrix” that includes the angular variation
of the scattered object waves, and we have adopted a special
average process and the gradient projection method for minimizing
the mean-squared error. The reconstruction of the 
bulk
structure is demonstrated by using an experimental 
single-energy hologram. The holographic reconstruction
provided a three-dimensional image with a size of 10
along both the vertical and horizontal axes.
