Color hologram display and its fabrication process
First Claim
1. A process of fabricating a color hologram display, comprising recording a color three-dimensional subject image and a color pattern of plane characters or images as hologram images by exposing a subject hologram plate for forming the color three-dimensional subject image and a character hologram plate for reconstructing the color pattern of plane characters or images, where the two plates are separately made, said subject hologram plate and said character hologram plate are spatially positioned with a given space located there between, and diffracted lights from said subject hologram plate and said character hologram plate are simultaneously entered in a same photosensitive material to record interference patterns for the images and reconstructed pattern of said subject and character hologram plates, with exposing light, as hologram images.

Abstract
The invention relates to a color hologram display an image of a three-dimensional object and a hologram image of a pattern of plane characters, images or the like are recorded in the same volume type hologram photosensitive material in a superposed or multiplexed fashion. A color hologram display 27′ comprising a combined reflection and volume type of single layer, wherein a color pattern 29g of plane characters, images or the like and a color three-dimensional subject image O″ are reconstructably recorded while spatially superposed one upon another.
