摘要： The invention is intended to represent a three-dimensional image of an object just as observable from a viewing point, allowing representation of a semi-transparent image on the condition that its rear side may not transparently visible. A three-dimensional image display device according to the present invention is composed essentially of a laser light source, a modulator, an X-Y deflector, a control computer, an image data memory, a moving flat screen and a projection lens. The screen is constructed of a large number of pixels (e.g., 100 by 100 pixels) and each of the pixels is composed of a large number of diffraction elements (e.g., 5 by 5 diffraction elements). On the basis of three-dimensional image data and desired view-point data, both control and image-data preparing computers perform ON-OFF control of laser radiation onto diffraction elements having different reflection directions to determine displaying condition of a pixel composed of said diffraction elements.

摘要： 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.
