Methods of making holographic images

摘要

A process of making holographic images comprising the steps of recording a hologram of a parallax limited aerial image formed by a lens on a recording surface with a reference beam at an angle of incidence to the recording surface that is preferably equal and opposite to the angle of incidence of the object beam to the recording surface, and illuminating the hologram with a beam of diverging or collimated light, preferably at the angle of incidence of the object beam to the recording surface and directed oppositely to the direction of the object beam during recording. Illumination can be with white light. The hologram may comprise superposed recordings of the aerial image made with light of different wavelengths to produce full color holographic images.
