DEVICE FOR GENERATING THREE-DIMENSIONAL IMAGES

摘要

The present invention relates to a device for generating a three-dimensional image of an object, wherein said device provides for a wider observation angle of said image and consists of a projection device. This device comprises several pairs of positive lenses arranged in the form of a telescopic system as well as two prismatic screens, wherein one screen is arranged on the focalisation planes of the lenses while the second is arranged in front of the first lens. Each prismatic screen comprises two screens which are oriented at an angle of 90 DEG relative to each other about their optical axis, and that each include a set of wide Dové's prisms which are arranged by pairs with their reflective sides facing each other. The prismatic screen can also be replaced with a lenticular screen comprising three identical plates each comprising a large number of lenses. The distance between these plates is selected so that each set of three lenses forms a telescopic system. The object to be projected is formed by a raster screen according to a holographic method or other methods.
