“…The motion parallax multi-view 3D displays have been proposed in literature using light field displays, head-mounted displays, and holographic display systems. The light field based motion parallax displays use the concept of rays projections in 3D space to address the parallax depth cue [15][16][17]. The full parallax multi-view 3D displays are realized by using holography in which the light wave pattern is produced using spatial light modulators [18,19].…”

We propose an integrated 3D image capture and display system using a transversely moving camera, regular 2D display screen and user tracking that can facilitate the multi-view capture of a real scene or object and display the captured perspective views in 3D. The motion parallax 3D technique is used to capture the depth information of the object and display the corresponding views to the user using head tracking. The system is composed of two parts, the first part consists of a horizontally moving camera interfaced with a customized camera control and capture application. The second part consist of a regular LCD screen combined with web camera and user tracking application. The 3D multi-view images captured through the imaging setup are relayed to the display based on the user location and corresponding view is dynamically displayed on the screen based on the viewing angle of the user with respect to the screen. The developed prototype system provides the multi-view capture of 60 views with the step size of 1 cm and greater than 40˚ field-of-view overlap. The display system relays 60 views providing the viewing angle coverage of ±35˚ where the angular difference between two views is 1.2˚.

“…As the great innovation of three-dimensional (3D) display technology and the urgent needs of information display, the research of tabletop 3D display has attracted more attention and made great progress [ 1 , 2 , 3 ]. The conventional tabletop 3D displays, such as holographic 3D display [ 4 , 5 , 6 ], integral imaging 3D display [ 7 , 8 , 9 ], volumetric 3D display [ 10 , 11 , 12 ], light-field 3D display [ 13 , 14 , 15 ] and Microstructure-based 3D display [ 16 , 17 , 18 ], can provide more information and more realistic 3D scenes. However, the inherent drawbacks limit the application of tabletop 3D displays, for example, the shallow depth of field, the low viewing resolution and the viewing jump.…”

Since the effect of the facet braiding phenomenon, the display quality of reconstructed image degrades with increasing depth of field in tabletop three-dimensional light-field display. Here, to analysis the facet braiding, the imaging process of the tabletop 360-degree three-dimensional light-field display based on conical lens array is mathematically modeled. A viewpoint-fitting encoding algorithm is proposed to reduce the effect of the facet-braiding phenomenon and improve the range of depth of field, which is optimized to form the best synthetic encoded image by fitting the reconstructed image seen by the simulated human eye to the parallax image captured at the corresponding location. The effectiveness of the proposed optimization algorithm is verified by simulation analysis and optical experiments, respectively. In the experiment, the clear depth of field range of the display system is increased from 13 cm to 15 cm, and the visualization effect of the reconstructed three-dimensional image is enhanced.

“…In essence, the insufficient density of information received by a monocular leads to VAC [4][5][6] . Therefore, researchers put forward the scheme of super multi-view display with the viewpoint interval smaller than the pupil diameter [7][8][9] . As shown in Fig 1 .c, a point on the stereo virtual image will have two or more rays entering the pupil.…”

This paper designs a binocular three-dimensional (3D) display based on pixelated nanograting matrix. A view modulator covered with the nanograting matrix forms a specific view distribution according to the binocular position in space. Furthermore, we introduce the concept of super multi-view display to resolve the vergence-accommodation conflict (VAC). In the experiment, we combine the LCD screen and the view modulator pixel by pixel. Then a binocular super multi-view 3D display prototype is constructed with collimation backlight. The experiment demonstrates that this scheme can present stereoscopic images with correct depth cues.
