Electron holography

Electron Holography was devised for breaking through the resolution limit of electron microscopes. The advent of a "coherent" field-emission electron beam has enabled the application of electron holography in various areas of magnetic-domain-structure observation, fluxon observation in superconductors, and fundamental experiments in physics, which have been inaccessible using other techniques. After examining the fundamentals of electron holography and its applications to the aforementioned fields, a detailed discussion of the Aharonov-Bohm effect and related experiments is presented.
