“…Viewing through parallax barriers and lenticular sheets are the dominant autostereoscopic technologies [3][4][5]. Compared to the low transmittance of parallax barrier, lenticular sheet-based technique is better for outdoor use [6]. Pixels in autostereoscopic displays (ADs) are classified to display stereo images of different views, and every view of stereo images are directed into different regions by parallax barriers or lenticular sheet.…”

Autostereoscopic displays employing lenticular sheets have broad applications due to the high transmittance of lenticular sheet. However, due to the restriction of lens array design and processing, the imperfect image of lenses can reduce the quality experience of autostereoscopic displays. Stereo depth is one of the qualities of experience parameters, which relates to the three-dimensional effect. Therefore, to quantize the reduction effect of stereo depth caused by lens aberration is of great value. In this paper, we implement a binocular model of an autostereoscopic display system with lens array to analyze this effect, which is different from the previously used monocular model. Two receivers in the positions of viewer’s eyes are set on the viewing plane, and a similar factor is defined to evaluate the difference of light spots perceived by the two receivers. When the similar factor exceeds a certain value, the two spots cannot be fused in the brain, thus restricting the perceived stereo depth. Both in simulation and experiment, a sudden decrease of the similar factor is observed when the viewing angle exceeds 16°. In the subjective experiment, all the sixteen viewers feel a sudden decrease of stereo depth when the viewing angle exceeds 16°, which further verifies the validity of the model. The model and the method are significant for improving the viewing experience of autostereoscopic displays and providing a guidance on autostereoscopic display system designing.

“…1 So, the neareye 3D display has become a hot spot today. [2][3][4][5][6] Existing commercialized near-eye 3D display products depend on stereoscopic technology, 7,8 which projects only one perspective view to each eye of the viewer and results in loss of monocular depth cues. For a displayed spatial point, the convergence of the two passing-through cone-shaped beams coming from the two perspective views on the screen gives a virtual 3D depth perception to the user, as shown in Fig.…”

Based on temporal-multiplexing, super multi-view (SMV) technology gets implemented on a near-eye three-dimensional (3D) display, successfully overcoming the vergence accommodation conflict (VAC). The proposed system has two eyepieces for two eyes, respectively, each of which is constructed by an organic light-emitting diode (OLED) micro-display, a projecting lens, and a gating-aperture array. The gating-aperture arrays, consisting of gating apertures with an interval smaller than the diameter of the viewer's pupil, are attached to the projecting lenses and gate different spatial segments of the projecting lens's exit aperture in time sequence. Through refreshing the corresponding display contents synchronously, two or more light rays passing through a displayed point are guided by the gating-aperture array into each eye sequentially. Based on the persistence of vision, these light rays converge into a spatial light spot that the eye can focus on naturally, thus enabling a consistence between focusing distance and convergence distance. Further, gating-aperture array with polarization characteristics is designed to get a larger field of view (FOV), accompanied by a half-wave variable retarder being inserted between the OLED micro-display and the gating-aperture array in each eyepiece. Employing two OLED micro-displays of 120-Hz frame rates, a near-eye 3D display prototype has been demonstrated with an FOV 40 deg and a display frequency of 40 Hz, being free from VAC.

“…However, the holographic technologies still have some disadvantages for commercial purposes, such as the need to improve the video‐rate so that the viewer does not experience any lag or flicker problem. Even though the disadvantages exist, the naked‐eye 3D imaging had already proven desirable for social media users because of its obvious benefits, in which the viewer does not need to wear the heavy glasses beside it is more likely to be transported into mobile terminals including display modules, where the increasing ability to produce the naked‐eye 3D imaging has almost actualized for commercial purposes . Henceforth, many investigations have used the advantages of micro/nanomaterial technologies, to serve the large demands of users, where the functional 3D imaging is required.…”

We present a design of micro‐conjugate mirror using a nonlinear microring resonator, which is made of GaAsInP/P, is rapidly achieving widespread option in several three‐dimensional (3D) imaging applications. By exploiting the conjugate mirror properties, the 3D light probes can be formed by the whispering gallery modes (WGM) in which the WGM probe is also available within a nonlinear microring resonator. It is important to understand, these light probes use the similar functional principle to provide structured light through the object, just as the reference beams to light up and develop a hologram using the holographic method. The interference of 2 beams constructs the 3D image which can be seen by the naked‐eye while providing the 3D perception. The simulation results obtained from the transmission of 3D imaging are processed using MATLAB and OptiFDTD are compared and analyzed. These convincing theoretical results suggest that the proposed method can be used in practice to realize the naked‐eye 3D imaging with convincing visual perception and efficient transmission while providing the ultimate mode of convenience for viewers.
