ABSTRACT:
A three-dimensional image display device capable of displaying a wide screen three-dimensional image which one can easily observe from any position and direction in the same way as viewing an existing object and which device can select display conditions not to allow a three-dimensional image to be semi-transparent, and a method for making said device. Three-dimensional image data includes image data and data on relative positions of each image point (pixel). A screen panel is composed of a plurality of elementary holograms for producing diffracted light for forming each point-image on a three-dimensional image (said elementary hologram is prepared by the method according to the present invention). On the basis of the three-dimensional image data, a control computer controls a modulator and X-Y deflector so that elementary holograms on the screen panel is illuminated one by one with modulated light by raster scanning of a laser light to represent a three-dimensional image composed of point-images. Modulation control is conducted by judging each point-image to be seen and selecting relating elementary holograms to be illuminated.
