What is atomic holography?

Atomic holography:

Atomic holography has evolved out of the growth of the fundamental elements of atom optics. Along with the Fresnel diffraction lens and atomic mirrors atomic holography obeys a natural step into the development of the physics and applications of atomic beams. Current developments including atomic mirrors and particularly ridged mirrors have given the tools essential for the creation of atomic holograms, though such holograms have not still been commercialized.
