We present a method for spatially resolved imaging of energy-dependent photoelectron diffraction. Energy-dependent photoelectron-diffraction spectra are individually Fourier transformed to three-dimensional vector space. The complex transformed amplitudes are summed over a span of Φ angles or over a span of polar angles. The images are, respectively, well resolved in the radial and azimuthal directions, or in the radial and polar directions. The intersections of these real-space maps fix the atomic coordinates. We show how the intensity loci from single and multiple scattering paths are separately resolved and how most multiple scattering contributions are eliminated
