Holographic optical elements (HOEs) exhibit several unique properties in arbitrary wavefront
recording and extraction. Versatile recording mechanisms and material availabilities further …

Extended reality (XR) refers to an umbrella of methods that allows users to be immersed in a
3D or a 4D (spatial+ temporal) virtual environment to various extents, including virtual reality …

We propose a new thin and flat virtual reality (VR) display design using a Fresnel lenslet
array, a Fresnel lens, and a polarization-based optical folding technique. The proposed …

An adaptive-focus lens is a device that is capable of tuning its focal length by means of an
external stimulus. Numerous techniques for the demonstration of such devices have been …

Wide field-of-view (FOV) optics are essential components in many optical systems, with
applications spanning imaging, display, sensing, and beam steering. Conventional …

In 2019, the device performances of the display technologies were largely advanced by the
development of new materials and of the device architecture and driving scheme. The recent …

With the help of augmented reality (AR) and virtual reality (VR) systems, users can receive
information and connect with each other via near-eye displays (NEDs). However, several …

We present a full-color holographic augmented reality near-eye display using a
Pancharatnam-Berry phase lens (PBP lens) and its aberration correction method …

We present a retinal-projection-based near-eye display with switchable multiple viewpoints
by polarization-multiplexing. Active switching of viewpoints is provided by the polarization …

Holographic optical element (HOE) can be used in many areas in optics due to its
characteristics of thin structure, flexible wavefront reconstruction/control ability and …
