ABSTRACT:
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.
