Real-time transmission of 3-D images formed by parallax panoramagrams

Theoretical and experimental investigations on the real-time transmission of 3-D images formed by parallax panoramagrams are described. At the image-taking station, a 3-D image is optically decomposed into line images, which can be directly handled by a high resolution TV set. By registering a lenticular sheet to the reproduced line images on a monitor screen, the reconstructed 3-D image is seen by the naked eye. By using an ordinary color TV set with a 350-line resolution and a cylindrical lens array with a 3-mm pitch, 3-D color images composed of thirty-five elements in the horizontal direction and seen from four directions are successfully transmitted and reconstructed with clear parallax.
