<title>Compatible 3-D Television: The State Of The Art</title>

Abstract

A brief review over the past and present work on stereoscopic and volumetric TV employing the conventional 2 -D TV equipments and standards has been made. The earlier 3 -D viewing systems such as direct -eye-contact types, color filter based techniques and polarization based systems are critically examined for a successful 3 -D TV. A bicircular polarization technique using electrooptic material in the picture tube screen is proposed for a 3 -D color TV.Also, a technique involving region -wise periodic illumination of the object for registering blur -free sectional images of the object needed for a volumetric 3 -D TV is proposed.
