Abstract
A method consisting in that the holographic image of an object is recorded on a substrate, a two-dimensional image of the same or any other object of interest is formed on a separate substrate, and the substrate with the holographic image is then so arranged with respect to that with the two-dimensional image that both images are oriented to produce the desired effect. The images are reconstructed through illumination by a light beam of varying intensity and spatial coherence.
