Dual-view-zone tabletop 3D display system based on integral imaging

Abstract

In this paper, we propose a dual-view-zone tabletop 3D display system based on integral imaging by using a multiplexed holographic optical element (MHOE) that has the optical properties of two sets of microlens arrays. The MHOE is recorded by a reference beam using the single-exposure method. The reference beam records the wavefronts of a microlens array from two different directions. Thus, when the display beam is projected on the MHOE, two wavefronts with the different directions will be rebuilt and the 3D virtual images can be reconstructed in two viewing zones. The MHOE has angle and wavelength selectivity. Under the conditions of the matched wavelength and the angle of the display beam, the diffraction efficiency of the MHOE is greatest. Because the unmatched light just passes through the MHOE, the MHOE has the advantage of a see-through display. The experimental results confirm the feasibility of the dual-view-zone tabletop 3D display system.

“…However, due to the accommodation-convergence mismatch caused by the stereoscopic technique [2], most of the head-mounted display (HMD) systems could result in users' uncomfortableness. True 3D display technique, such as holographic display [3,4], integral imaging [5,6], super multi-view display [7,8], volumetric display [9][10][11][12][13], is considered as effective solutions to solve such problem.…”

Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element

“…Integral imaging is considered to be one of the most promising display technologies. It has the advantages of full parallax [12] and continuous viewpoint [13], and it supplies various physiological depth cues, so viewers can freely change the accommodation and convergence without feeling any visual discomfort [14,15]. Integral imaging has a small viewing angle, and the viewing zone is periodically repeated.…”
