Electron Holography: A New View of the Microscopic

APR 01, 1990

Now that coherent field‐emission electron beams are available, one can exploit the wave nature of free electrons to do holography on the atomic scale.

Holograms generally record interference patterns produced by visible light. But one can, in principle, make use of any coherent wave phenomenon. One can, for example, create a hologram by recording on film the interference pattern of an object formed with electron beams. One can then reconstruct the three‐dimensional optical image of the object by illuminating this hologram with a laser beam. This imaging technique, which is called electron holography, transforms an electron wavefront into an optical wavefront. In this way, one can exploit versatile optical techniques to do interesting and useful things that are simply not feasible with pure electron microscopes.
