Dual-view holographic three-dimensional display using a single spatial light modulator and a directional light-guide plate composed of pixelated gratings

摘要

In this paper, a dual-view holographic three-dimensional (3D) display using a single spatial light modulator (SLM) and a directional light-guide plate (DLGP) is proposed and implemented. The SLM is used to load the phase-only hologram calculated from two different 3D scenes for optical holographic reconstruction, and the DLGP composed of pixelated gratings with different periods and orientation angles is employed to guide the reconstructed images into two completely separated viewing zones, where different reconstructed perspectives in each viewing zone will form a stereoscopic 3D image. Furthermore, an experimental verification system for the proposed dual-view holographic 3D display is constructed, and the experimental results demonstrate that the proposed system can successfully present different 3D images in the left and right viewing zones simultaneously, verifying the feasibility of the proposed dual-view holographic 3D display.
