The invention relates to displaying stereoscopic images and can be used in television broadcasting, computing, control and management systems, CAD, game technology, for developing training simulators, in avionics and instrument making, in science, education, medicine, etc. for solid modeling and the visual representation of static and dynamic processes in 3D. The autostereoscopic system comprises a visualization surface provided with an image which has been prepared for separation, said image consisting of a sequence of m perspectives, each of which alternates with a frequency of no less than the physiologically conditioned sensitivity of the human eye, and a dual raster screen which is positioned in front of the visualization surface and consists of two rasters disposed on opposite sides with respect to a common focal plane which diffuses a stream of light; each raster consists of lens elements which are contiguously disposed on the surface and form coaxial pairs; furthermore, each pair is provided with m eclipse shutters, each of which opens synchronously with the sequence of perspectives, the dual raster screen is disposed in front of the visualization surface at a distance at which the optical projection of a part of a raster unit h m = h / m from the common focal plane of the dual raster onto the surface of the visualization surface is equal to the raster unit h. The technical result of the claimed invention consists of determining the interrelation of the optical structure parameters of the autostereoscopic system at which the stereoscopic image will be of the highest quality. |
