“…These include using various methods for input and output for 3D light field rays. For example, light field rays can be collected and/or displayed through detectors and display pixels and lenslet arrays, microlenslet arrays [19], diffractive optics, holographic elements, parallax barrier techniques [20], spatial light modulators, other methods, or a combination of these.…”

A switchable virtual reality (VR), augmented reality (AR), and mixed reality (MR) system is proposed using digital optical cloaking. Optical cloaking allows completely opaque VR devices to be "cloaked," switching to AR or MR while providing correct three-dimensional (3D) parallax and perspective of the real world, without the need for transparent optics. On the other hand, 3D capture and display devices with non-zero thicknesses, require optical cloaking to properly display captured reality. A simplified stereoscopic system with two cameras and existing VR systems can be an approximation for limited VR, AR, or MR. To provide true 3D visual effects, multiple input cameras, a 3D display, and a simple linear calculation amounting to cloaking can be used. Since the display size requirements for VR, AR, and MR are usually small, with increasing computing power and pixel densities, the framework presented here can provide a widely deployable VR, AR, MR design.

“…Because the light field 3D display is formed by the convergence of dense geometric rays based on SMV technology, it can more truly reproduce the stereoscopic image with spatial depth information. Moreover, the light field 3D display technology is easy to integrate on flat-panel display, which meets the consumer demand of portable electronic devices [8][9][10][11] and has great commercial development prospects [12].…”

In naked‐eye 3D display, the light field display has been widely concerned because it can provide vivid and natural 3D performance, and light field display technology based on super‐multi‐view (SMV) has also become an important research direction of naked‐eye 3D display. However, insufficient viewing angle is one of the main factors limiting the development and application of light field display technology. In this paper, we propose a wide‐angle‐splicing display method for dynamic backlight system based on the light field display with SMV technology. The experimental results show that the viewing angle is increased by about 50% from the original 60° to more than 90°, and a time‐multiplexed light field display with a 90° wide viewing angle is demonstrated. At the same time, it can provide the viewer with smooth and continuous motion parallax, and clear 3D images can be perceived at the entire range of viewing angle, which greatly improves the viewer's visual experience.

“…A parallax barrier (PB) is a well-known method to realize an autostereoscopic 3D display without special glasses [15][16]. Since a PB is already verified by having been used in various commercial autostereoscopic 3D displays, it can be a practical solution to realize a 3D transparent display.…”

A Three-dimensional Transparent Display with Enhanced Transmittance and Resolution Using an Active Parallax Barrier with See-through Areas on an LCD Panel

The transmittance of the three dimensional (3D) transparent display is an important factor and can be enhanced by adding a see-through area to the displayed 3D image in order to transmit an ambient light with maximum transparency. However, there is a side effect that the perceived 3D resolution can be degraded due to the see-through area. In this paper, we propose an advanced method to resolve the above trade-off relation between the transparency and the 3D resolution by using an active parallax barrier (PB) with a see-through area. The experimental results are also presented to prove the proposed principle.
