Abstract
In connection with its work 'high-resolution television' the Heinrich Hertz Institute, Berlin, is investigating the feasibility of a large-screen image with a three-dimensional effect which, in contrast to previous processes, may be viewed without the aid of special glasses. A pilot study has been made in recording and reproducing so-called parallax panoramagrams by photo-optical means. Sequentially photographed stereo images were projected through several projectors onto a lens screen, a large-surface collector which by means of directional selection permits the reproduction of image depth. The author discusses how the geometric-optical problems involved in filming, photographing, projecting and transmission were solved, goes into the mathematics, and outlines experiments on the realization and optimization of this image transmission method.
