“…The image quality for performance is not well enough, it is mainly due to the speckle noise caused by the temporal and spatial coherence of the collimated laser beam used to shine the hologram and the initial random phases imposed on the holographic image during the calculation process. In fact, many approaches have been presented to reduce it, such as averaging the speckle noise using high‐speed refreshing multiple holograms, double phase encoding [ 9 ] , and camera‐in‐the‐loop neural network algorithm [ 11 ] . These techniques can be introduced to improve the image quality when a dynamic metasurface based SLM is available in the near future.…”

“…[7,8] In the first several works, the optical components should be set on the optical bench, with the limited spatial resolution of the virtual image. Thanks to the optimization of the system [9,10] and the introduction of the neural network, [11][12][13] part of the system can be compact and the spatial resolution has been improved. Due to the remarkable progress, more intentions from both academia and industry have been paid within these two years.…”

Most of current commercial near‐eye 3D displays use traditional stereoscopic approach to generate the 3D information. A well‐known issue for this type of technology is the vergence and accommodation conflict, which leads to visual confusion and fatigue for the viewer. To address this problem, a proof‐of‐concept solution based on retinal projection technology has been developed to provide accommodation‐free virtual images by using a small aperture (360 µm × 360 µm) transparent Huygens’ metasurface hologram as the display device. The virtual image is generated using a visible laser illuminating a metasurface hologram, which is then directly projected onto the retina using an optical see‐through eyepiece. Using this concept, this work experimentally demonstrates a compact and wearable near‐eye display of light weight (≈50 g, including spectacle frames, light source, and battery) creating accommodation‐free images (clear ranging from 0.5 to 2 m), overlaid with the real world and directly viewed by naked eye. To do so, a new design method is introduced for retinal projection near‐eye displays that, inherently, is able to solve the vergence‐accommodation conflict using a small aperture Huygens’ metasurface hologram.

“…It also offers unique benefits such as aberration-free high resolution images, per-pixel depth control, vision correction functionality [16][17][18] , as well as large color gamut. Recently, a lot of progress has been made in the field of computer-generated hologram (CGH) rendering, getting more attentions from the industry [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] . Many conventional issues of holographic displays such as speckle, image quality issue, and heavy computation load are demonstrated to be solved by aid of better CGH rendering model and improved computation power of recent graphics processing units (GPU) [34][35][36][37] .…”

We present a novel near-eye display concept which consists of a waveguide combiner, a spatial light modulator, and a laser light source. The proposed system can display true 3D holographic images through see-through pupil-replicating waveguide combiner as well as providing a large eye-box. By modeling the coherent light interaction inside of the waveguide combiner, we demonstrate that the output wavefront from the waveguide can be controlled by modulating the wavefront of input light using a spatial light modulator. This new possibility allows combining a holographic display, which is considered as the ultimate 3D display technology, with the state-of-the-art pupil replicating waveguides, enabling the path towards true 3D holographic augmented reality glasses.

“…However, most recent developments overlook the prevalence of refractive vision problems such as myopia, hyperopia, or astigmatism among potential VR users at least 23.9%, 8.4%, and 33% of the population, respectively [2]. Moreover, while the current near-eye display research is focused on the miniaturization of the headset to eyeglasses form-factor [3,4], wearing prescription glasses under a VR headset causes uncomfortable viewing experiences that break the feeling of immersion.…”

A large portion of today\'s world population suffers from vision impairments and wears prescription eyeglasses. However, prescription glasses causes additional bulk and discomfort when used with Virtual Reality (VR) headsets, negatively impacting the viewer\'s visual experience. In this work, we remedy the usage of prescription eyeglasses with screens by shifting the optical complexity into the software. Our proposal is a prescription-aware rendering approach for providing sharper and more immersive imagery for screens, including VR headsets. To this end, we develop a differentiable display and visual perception model encapsulating the human visual system\'s display-specific parameters, color, visual acuity, and user-specific refractive errors. Using this differentiable visual perception model, we optimize the rendered imagery in the display using gradient-descent solvers. This way, we provide prescription glasses-free sharper images for a person with vision impairments. We evaluate our approach and show significant quality and contrast improvements for users with vision impairments.
