Abstract (en)
[origin: WO2005032152A1] The invention relates to methods and arrangements for unaided three-dimensionally recognizable representation. The aim of the invention is to render the 3D optical structure as unresolvable as possible to the naked eye while improving the quality of the three-dimensionally recognizable representation. Said aim is achieved by a method for three-dimensionally recognizable representation, in which a plurality of individual image elements (alphaij) are simultaneously made visible, said image elements (alphaij) reproducing partial information from several views (Ak (k=1 ...n)) of the scene/object. Directions of propagation are predefined for the light emitted by the image elements (alphaij) with the aid of a structural plate. For this purpose, the structural plate is provided with a plurality of optical elements that are arranged in sequences. According to the invention, the mean geometrical distance (p') between two adjacent sequences of light-transmitting optical elements on the structural plate meets the condition p' = p, wherein p=G*sin(0.017°), G representing four times the diagonal length of the image element (alphaij) raster. Also disclosed are arrangements for implementing the inventive method.
