10-9 Volumetric 3-D display by use of birefringent lens and projector array

Abstract

We propose a new volumetric 3-D display by use of multi-varifocal lens and high-speed 2-D display. The high-speed multi-varifocal lens is composed of several sets of a birefringent lens and a polarization switching device. We have developed a high-speed 2-D display that is composed of an array of 4×4 projectors with LED light sources. The proposed volumetric 3-D display has been successfully realized by switching projectors quickly with synchronizing the multi-varifocal lens.
