Abstract:
A hologram recording film has an image of a three-dimensional object, e.g. a three-dimensional model, recorded in a volume hologram photosensitive material and further has a hologram image of a plane color pattern, e.g. a character or an image, together with the shadow of the color pattern, recorded as individual information in a superimposed manner in the same photosensitive material without using a liquid crystal display. Pieces of plane additional information of the same pattern have been recorded so as to be capable of being reconstructed simultaneously in a hologram plane and in front of or behind the hologram plane, respectively, in superimposition with a reconstructed image from a volume hologram.
