“…The viewing angle was 20.8 • , and the diffraction efficiency of the holographic combiner (73.6 × 41.4 mm 2 ) for the wavelength of 532 nm was 52.9% [23]. In another strategy, a holographic optical element with a size of 80 × 80 mm 2 acted as a lenticular lens array at the Bragg-matched condition [24]. Our group designed a spatial multiplexing holographic see-through combiner based on pixelated metagratings.…”

Glasses-free augmented reality (AR) 3D display has attracted great interest in its ability to merge virtual 3D objects with real scenes naturally, without the aid of any wearable devices. Here we propose an AR vector light field display based on a view combiner and an off-the-shelf purchased projector. The view combiner is sparsely covered with pixelated multilevel blazed gratings (MBG) for the projection of perspective virtual images. Multi-order diffraction of the MBG is designed to increase the viewing distance and vertical viewing angle. In a 20-inch prototype, multiple sets of 16 horizontal views form a smooth parallax. The viewing distance of the 3D scene is larger than 5 m. The vertical viewing angle is 15.6°. The light efficiencies of all views are larger than 53%. We demonstrate that the displayed virtual 3D scene retains natural motion parallax and high brightness while having a consistent occlusion effect with natural objects. This research can be extended to applications in areas such as human–computer interaction, entertainment, education, and medical care.

“…Although the 3D display can be achieved by optical path folding, the system volume becomes very large. Recently, the opaque issue of II is solved by replacing the lens arrays with the lens-array holographic optical element (LAHOE) [15][16]. In addition, LAHOE has the advantages of high transparency and high diffraction efficiency as well as being very compact.…”

“…The technology that is key to realizing optical see-through AR display is the image combiner that overlaps the virtual images and the real scenes together. The image combiner can be further divided into two categories: reflection-type devices [15,16] and diffractiontype devices [17,18]. Compared with reflection-type devices, the diffraction-type devices have many advantages, such as unique angle selectivity and wavelength selectivity and flexibility of design, as well as high diffraction efficiency and transparency.…”

An optical see-through two-dimensional (2D)/three-dimensional (3D) compatible display using variable-focus lens and multiplexed holographic optical elements (MHOE) is presented. It mainly consists of a MHOE, a variable-focus lens and a projection display device. The customized MHOE, by using the angular multiplexing technology of volumetric holographic grating, records the scattering wavefront and spherical wavefront array required for 2D/3D compatible display. In particular, we proposed a feasible method to switch the 2D and 3D display modes by using a variable-focus lens in the reconstruction process. The proposed system solves the problem of bulky volume, and makes the MHOE more efficient to use. Based on the requirements of 2D and 3D displays, we calculated the liquid pumping volume of the variable-focus lens under two kinds of diopters.
