ABSTRACT:
Device for reproducing stationary or three-dimensional images by projection, the photographing being effected through several objectives, each located at a different position in space; in the reproduction system, the different images, if not reproduced on a diffusion surface, do not need to be distinguished by their position on it; the projection is effected directly onto a transparent optical system, the images being distinguished from each other by their angle of projection; this optical system is formed of a sheet of vertical cylindrical lenses, the transverse size of which is not conditioned by the number of images and the aperture of which is independent of the orthoscopic viewing angle, and of a sheet of horizontal cylindrical lenses of short focal length and arbitrarily small size constituting a reproduction system which is easy to manufacture and can be adapted to any viewing angle, giving a different image at each point of viewing.
