Holography With Electrons

The principle of holography was discovered in 1947 by the Hungarian scientist Dennis Gábor, in connection with attempts to improve the resolution of electron microscopes. The experimental realization of the concept of holography had to wait, however, until the mid-60s. Holograms were then made using newly-discovered laser light sources, rather than with electrons. Physicists from the Max Born Institute in Berlin have now returned to the use of electrons in holography. A special element in their approach is that the electrons that image the object are made from the object itself using a strong laser... Read More

Experimentally measured velocity map image for the ionization of metastable Xe atoms by 7 micrometer light from the FELICE laser. The image shows the velocity distribution of the ionised electrons along (horizontal) and perpendicular to (vertical) the polarization axis.
