TL;DR: A holographic wavefront sensor scheme based on a phase-only spatial light modulator, which is used for CGH displaying, is proposed and the presented optical scheme and processing algorithm are validated with numerical simulations and experimental modelling.
Abstract: The present article is dedicated to the problem of computer-generated holograms application for measurement of optical wavefront curvature with high precision. A holographic wavefront sensor scheme based on a phase-only spatial light modulator, which is used for CGH displaying, is proposed. The presented optical scheme and processing algorithm are validated with numerical simulations and experimental modelling.

TL;DR: An augmented reality display based on a planar waveguide made in photo-thermo-refractive glass had been demonstrated and the monolithic integration of multiplexed volume Bragg gratings with the waveguide platform provided in/out-coupling and image transmission from a portable projector.
Abstract: An augmented reality display based on a planar waveguide made in photo-thermo-refractive glass had been demonstrated. The monolithic integration of multiplexed volume Bragg gratings with the waveguide platform provided in/out-coupling and image transmission from a portable projector. Design and calculation of the grating configuration was performed. The optical replication method was simulated and implemented for manufacturing the multiplexed coupling elements. Resulted field of view was limited by the projection system of the prototype, however can be expanded beyond 50o.

Abstract: The holographic optical elements (HOE) for holographic indicators and methods of their production on the photosensitive materials are described. A distinctive feature of this optical scheme is the zone record of diffraction gratings and HOE, i.e., grating is divided into separate fragments that stitching at the recording process with a high-precision motion system of the plate.

TL;DR: A combination of holographic and diffractive optical elements (HOE-DOEs) for multicolor signs-symbolic information display system, screens and indicators is described in this article.
Abstract: A combination of holographic and diffractive optical elements (HOE-DOEs) for multicolor signs-symbolic information display system, screens and indicators is described. These elements combine the functions of high-efficiency four-level diffractive optical elements with spectral plasmon filters having a variable bandwidth dependent on the angle of incidence. The main parameters of such HOE-DOEs were determined using the Fourier modes method. The theoretical results show that a four-level diffraction grating and a plasmon filter can be combined based on their spectral-angular characteristics, opening up the possibility for their use in display systems.

TL;DR: In this paper, the authors used the pressure of light, also called optical forces or sometimes "tractor beams", to create a new type of rewritable, dynamic 3D holographic material.
Abstract: Researchers have used the pressure of light—also called optical forces or sometimes "tractor beams"—to create a new type of rewritable, dynamic 3D holographic material. Unlike other 3D holographic materials, the new material can be rapidly written and erased many times, and can also store information without using any external energy. The new material has potential applications in 3D holographic displays, large-scale volumetric data storage devices, biosensors, tunable lasers, optical lenses, and metamaterials. [21]

TL;DR: In this article , a gaze-matching augmented reality (AR) system with an enlarged eyebox is demonstrated, where two layers of cholesteric liquid crystal (CLC) lenses are applied as the optical combiner in the system, which is lightweight and compact.
Abstract: Maxwellian‐view structure exhibits several advantages in augmented reality (AR) displays, such as high efficiency, always‐in‐focus (no vergence‐accommodation conflict (VAC)), and simple optical structure. However, the bottleneck of Maxwellian‐view is its tiny eyebox. Extensive efforts have been devoted to enlarge the eyebox of the Maxwellian‐view system based on pupil duplication or pupil steering by creating multiple viewing points, however, the important gaze matching is neglected. Once the virtual image center deviates from the user's eye gaze, it will bring an unnatural viewing experience. Herein, a gaze‐matching Maxwellian‐view AR system with an enlarged eyebox is demonstrated. In the meantime, this AR system also maintains the properties of aberration‐free, high efficiency, highly transparent for ambient light, and relatively large field of view. Moreover, two layers of off‐axis cholesteric liquid crystal (CLC) lenses are applied as the optical combiner in the system, which is lightweight and compact. The off‐axis angle of such a CLC lens is as large as 60 degrees, which plays a vital role in future Maxwellian‐view AR headsets.

TL;DR: In this article, an algorithm that automatically calculates aberrations in the holographic wavefront sensor scheme was described, which enables measuring aberration by means of iterative generation of holograms on a phase spatial light modulator (SLM).
Abstract: An algorithm that automatically calculates aberrations in the holographic wavefront sensor scheme previously proposed by the authors is described, which enables measuring aberrations by means of iterative generation of holograms on a phase spatial light modulator (SLM). The practical implementation of this algorithm on the basis of the feedback of the camera and SLM is given. Using the proposed algorithm, defocusing was measured with an accuracy of λ/160.
