holography

holography (In French holographie) photography that allows the spatial reproduction of a scene in a special recording medium. For color holography, single-color laser beams in the colors RGB are directed onto the scene to be reproduced; the reflected and scattered light form a wave pattern which, together with the original beams, forms a common interference pattern, which is then recorded photographically. This hologram develops its 3D effect in all light whose spectrum contains sufficient red, green and blue components.
