Stereoscopic Microscopy of Atomic Arrangement by Circularly Polarized-Light Photoelectron Diffraction

Abstract

A principle for stereoscopic photographs that enables viewing three-dimensional atomic arrangements is proposed. The azimuthal shifts of forward-focusing peaks in the photoelectron diffraction pattern obtained by left and right helicity lights enables a stereoscopic image when the two images are, respectively, viewed by the left eye and the right eye simultaneously. By taking advantage of this phenomenon, a display-type spherical-mirror analyzer can obtain stereoscopic photographs directly on the screen without any computer-aided conversion process.
