Liquid crystal (LC) circular polarization gratings (PGs), also known as Pancharatnam–Berry
(PB) phase deflectors, are diffractive waveplates with linearly changed optical anisotropy …

Three-dimensional (3D) displays have been vastly investigated in the past few decades.
Recent development of augmented reality (AR) and virtual reality (VR) has further …

The depth of focus (DOF) of a lens is a crucial parameter in glasses-free 3D displays that
affects the viewing distance range. Here we proposed a vector light field display based on …

Conventional optical see-through integral imaging display system using holographic optical
element (HOE) is actually in focused display mode whose central depth plane (CDP) is very …

In lens-based display systems, lens aberrations and depth of field (DoF) limitation often lead
to blurring and distortion of reconstructed images; Meanwhile, expanding the display DoF …

Hydrogels have emerged as prototypical stimuli‐responsive materials with potential
applications in soft robotics, microfluidics, tissue engineering, and adaptive optics. To …

In this Letter, transverse and longitudinal liquid crystal bifocal lenses (LCBLs) are proposed
to continuously control the relative intensity of two foci through a simple polarization control …

It is difficult to find the micromirror array with desired specifications for augmented-reality
displays, and the custom fabricating methods are complicated and unstable. We propose a …

An integral imaging microscopy (IIM) system with improved depth-of-field (DoF) using a
custom-designed bifocal polarization-dependent liquid-crystalline polymer micro lens array …

Depth of field (DOF) is one of the important parameters of three-dimensional (3D) displays. A
two-dimensional (2D)/3D switchable display that can display both high-resolution 2D …
