Storage of one bit of information as a Hologram. a) Superposition of spherical wave from one bit with a coherent plane wave reference beam forming an interference pattern. b) Exposure of a photosensitive medium to the interference pattern. c) Record of the interference grating, stored as changes in the properties of the medium. Storage inside the Photosensitive Medium
