Stereoscopic viewing with PLZT ceramics

Abstract A new electro-optic shutter viewing device is described for use with stereoscopic real-time television and computer-driven CRT display systems. The high speed electronic shutters employ lead lanthanum zirconate titanate (PLZT) ferroelectric ceramics. The PLZT stereoscopic viewer represents significant improvements in performance and physical implementation over existing shutter viewing devices. Operational principles of PLZT stereoscopic viewers examined included CRT viewing geometry, synchronous PLZT shutter operation, and perceived visual effects. Also, pertinent PLZT shutter operating parameters are presented. Numerous application areas are identified, including airborne reconnaissance, remote vehicle control, and analysis of processed computer data.
