Physical Review Letters, 1994 The interference of the directly emitted photoelectron wave and the wave scattered coherently by neighboring atoms gives holographic fringes in the photoelectron emission intensity $I(\hat{\bf R})$. In the electron emission holography technique in surface physics, $I(\hat{\bf R})$ is inverted holographically to give a 3D-image of the environment of the

Out-of-focus holography at the Effelsberg telescope [PDF]
A&A 687, A27 (2024), 2021 Out-of-focus (OOF) holography can be used to determine aperture deformations of radio telescopes that lead to errors in the phase of the complex aperture distribution. In contrast to traditional methods, OOF holography can be performed without a reference antenna, which has a number of practical advantages. The aim of this work is to develop a standard
