Holographic-laser-excited volumetric graphics

Abstract

Volumetric displays with a laser excitation of screen materials make voxels in the real space. The laser drawing method can render volumetric graphics with a wide viewing angle because these is no physical wiring between drawing space and system to generate voxels. In our research, a holographic laser-drawing method based on a computer-generated hologram (CGH) displayed on a liquid-crystal on silicon spatial light modulator (LCOS-SLM) is used to increase the number of voxels per a unit time. In this presentation, we will present recent developments of the volumetric displays with the holographic laser drawing.
