Abstract
Due to the overlarge pixel pitch of the current available spatial light modulator (SLM), the separated angle of two reconstructed images is too small to realize dual-view holographic 3D display. At the same time, the reconstruction resolution is limited by the resolution of the SLM. In this paper, we propose a high-resolution dual-view display method based on holographic optical element (HOE) printed by computer-generated hologram (CGH). A synthetic phase only hologram of two different 3D objects is calculated by the layer-based angular spectrum diffraction method, and the digital grating is introduced to adjust the position of the reconstructed image. A HOE printed by CGH is used as the light guide plate to redirect the two reconstructed 3D images into the two separated viewing zones simultaneously. Optical experiments demonstrate that the proposed system can realize the function of high-resolution dual-view holographic 3D display
