Recently, metasurfaces composed of artificially fabricated subwavelength structures have
shown remarkable potential for the manipulation of light with unprecedented functionality …

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 …

Objective. This study aimed to design and evaluate a high-speed online steady-state
visually evoked potential (SSVEP)-based brain–computer interface (BCI) in an optical see …

The ultimate 3D displays should provide both psychological and physiological cues for
depth recognition. However, it has been challenging to satisfy the essential features without …

An augmented reality (AR) near-eye display using Pancharatnam-Berry (PB) phase lenses
is proposed. PB phase lenses provide different optical effects depending on the polarization …

The diffraction of polychromatic light from periodic superficial structures is often responsible
for the structural colors observed in Nature. Similarly, engineered microtextures fabricated …

Foveated near-eye display is one of the most promising approaches to deliver immersive
experience of mixed reality. However, it is challenged to conceive a compact optical system …

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

The possibilities that offer the holographic optical elements for photovoltaic and “see through
display” applications open new windows for holographic recording materials. In this sense …

A waveguide near-eye display (NED) with a dual-focal plane using a polarization-
dependent lens device is proposed. The novel optical device is composed of a geometric …
