The direct visualization of atomic arrangements is essential for understanding the nature of materials. The rotation of forward focusing peaks in photoelectron intensity angular distribution (PIAD) patterns excited by circularly-polarized light with the left and right helicities are found to be the same as the parallax in stereo-view. Moreover, this method is element selective since the photoelectrons from different core levels are used as a probe. Taking advantage of this phenomenon of PIAD circular dichroism, the three-dimensional atomic arrangement image of crystals and thin films were realized.
