electron holography

[i‚lek‚trän hō′läg·rə·fē]
(electronics)
An imaging technique using the wave nature of electrons and light, in which an interference pattern between an object wave and a reference wave is formed using a coherent field-emission electron beam from a sharp tungsten needle, and is recorded on film as a hologram, and the image of the original object is then reconstructed by iilluminating a light beam equivalent to the reference wave onto the hologram.
