This invention puts forward a method for displaying real 3-D images, in which, the device for realizing the method is composed of a paraboloid reflector, its servo system and a high speed electronic computer, a model of a being displaced 3-D color scenery is stored in the computer and the scenery can be expressed to n vertical sections. When a screen displays a frame of color images, a real image is formed near the reflector focus immediately, namely a section, the servo system moves the reflector one Cstep backward and the display screen displays the image of the next frame and a second real image of a second section is formed at the reflector focus, so n sections can be displayed orderly in so doing. Man-eye can see the complete 3-D color scenery when the renovation speed of the screen and the speed of the mobile paraboloid reflector of the servo system is so fast to reach the temporary sphere of man-eye vision. |
