WebFeb 7, 2015 · Yes, electron holography is possible and it is an exciting, growing research field within strong field physics. The nicest way to do this is via laser-induced holography, where you use a strong laser field to ionize a molecule and then drive the photoelectron back to the ion to make it recollide. The initial experiments looked at the way the ...

Gabor was seeking to improve the resolution and definition of the electron microscope; instead, he devised a new technique for creating images. Perhaps we have never been so …
WebElectron holography is a two-step imaging method devised by D. Gabor (Gabor, 1949): an electron hologram is formed as an interference pattern between an object wave and a reference wave, and the object electron wave is reconstructed as an optical wave by illuminating a laser beam onto hologram film. The reconstruction has been facilitated by WebOct 1, 2024 · Abstract. We examine the nature of the reconstructed 3D image as obtained by replay (or back-propagation) of the object wave from the hologram recording plane to the original object volume. While recording of a hologram involves transferring information from a 3D volume to a 2D detector, the replay of the hologram involves creating information ...
