Compatible volumetric 3-d tv systems: a proposal

Three types of 3-D TV system compatible with existing 2-D TV systems are proposed. These systems are not based on stereoscopic image techniques and do not impose any constraints on the viewer for 3-D perception. The first system makes use of the existing conventional color TV system for development of a 3-D TV system. The second system is based on the present monochromatic TV system. The third system depends on a light-emitting diode tank for 3-D display. To prove the validity of these systems a simulated experiment is demonstrated for the reproduction of a 3-D image using still photographs. All these systems are compared for their relative merits and demerits. © 1981 Optical Society of America.
