What is Electron Holography?
Electron holography is an application of holography procedures to electron waves quite than light waves. Electron holography was invented through Dennis Gabor to enhance the resolution and ignore the aberrations of the transmission electron microscope. Nowadays it is usually used to study electric and magnetic fields within thin films, as magnetic and electric fields can move the phase of the interfering wave passing by the sample. The principle of electron holography can as well be applied to interference lithography.
