Scientists make holograms of atoms using electrons

(PhysOrg.com) -- While holography is often associated with artistic 3D images, it can also be used for many other purposes. In a new study, scientists have created holograms of atoms using laser-driven electron motion, which could lead to a new type of ultra-fast photoelectron spectroscopy. In the future, this type of holography could enable scientists to study the structures of molecules in a more direct way than before.

Electron Holography: A New View of Material Structure

One day, while waiting to begin a tennis match, Gabor had a brilliant flash of intuition. The path leading to the formal development of his method of holography became instantly clear to him. The essence of the method was the combination of two waves within the microscope: the incident, undeviated electron wave and the image wave, which exits the bottom surface of the thin specimen. If the electron optical geometry is correctly set up, these two waves can be made to interfere. The interference pattern then would be processed using optical techniques to form optical holograms.
