Device for reproducing by projection still or moving tridimensional images, wherein the pickup is effected through various objectives situated, each of them, in a distinct spacial position; in the reproduction system, the various images, since they are not reproduced on a scattering surface, do not require to be distinguished by their position thereon; the projection is effected directly on a transparent optical system, the images being distinguished between each other by their projection angle; this optical system is comprised of a sheet of vertical cylindrical lenses whose cross-section size is not conditioned by the number of images and whose aperture is independent of the orthoscopic vision angle, and of a sheet of horizontal cylindrical lenses having a short focal distance and an arbitrarily small size forming a reproduction system easy to produce and adaptable to any angle of vision giving a distinct image at each observation point. |
