Monocular 3D see-through head-mounted display via complex amplitude modulation

Abstract

The complex amplitude modulation (CAM) technique is applied to the design of the monocular three-dimensional see-through head-mounted display (3D-STHMD) for the first time. Two amplitude holograms are obtained by analytically dividing the wavefront of the 3D object to the real and the imaginary distributions, and then double amplitude-only spatial light modulators (A-SLMs) are employed to reconstruct the 3D images in real-time. Since the CAM technique can inherently present true 3D images to the human eye, the designed CAM-STHMD system avoids the accommodation-convergence conflict of the conventional stereoscopic see-through displays. The optical experiments further demonstrated that the proposed system has continuous and wide depth cues, which enables the observer free of eye fatigue problem. The dynamic display ability is also tested in the experiments and the results showed the possibility of true 3D interactive display.

41.3: A flat‐panel holographic‐optical‐element system for holographic augmented reality display with a beam expander

“…There have been a few commercial AR displays such as Google Glass and Microsoft HoloLens [2,3]. However, in those products, the annoying accommodationconvergence conflict causes eye fatigue and discomfort .Several true 3D display methods, including holographic display [4][5][6][7][8][9], volumetric display [10][11][12], light field displays [1,[13][14][15][16], etc., have been incorporated into AR systems, aiming to address the accommodation-convergence conflict problem. Among the various 3D methods, holographic display offers efficient wavefront control by holographic superposition and optical aberration correction.…”

“…Thus, holographic technology holds great potential to realize 3D AR displays without eye fatigue. Several holographic AR displays have been realized, by combining holographic projection with different see-through eyepieces such as lenses with a beam-splitter (BSs) [4][5][6], holographic optical elements (HOEs) [7,8], waveguides together with HOEs [9].…”

“…Recently, 3D displays, including holography display [3][4][5], integral imaging display [6][7][8][9], volumetric display [10,11] and so on, have received extensive attention. Integral imaging is considered to be one of the most promising display technologies.…”

27.2: Invited Paper: True 3D displays for AR applications

“…Thus, holographic technology holds great potential to realize true 3D AR displays without eye fatigue. Several holographic AR displays have been proposed based on spatial light modulators (SLM) combined with a beam-splitter (BS) [20,21] or holographic optical elements (HOEs) [22][23][24]. However, current holographic displays are still immature for AR applications due to several limitations: small field of view (FOV), multiple diffractive orders, zero-order noise and so on.…”
