Paper Abstract

Two factors contributing to "ghosting" (image doubling) in plano-stereoscopic CRT displays are phosphor decay and dynamic range of the shutters. A ghosting threshold must be crossed before comfortable fusion can take place. The ghosting threshold changes as image brightness increases and with higher-contrast subjects and those with larger parallax values. Because of the defects of existing liquid crystal shutters, we developed a liquid-crystal shutter with high dynamic range, good transmission, and high speed. With these shutters, residual ghosting is a result of phosphor persistence.
