Reconfigurable metasurfaces provide nanoscale light control

Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve ...

New 3-D display takes the eye fatigue out of virtual reality

There is a great deal of excitement around virtual reality (VR) headsets that display a computer-simulated world and augmented reality (AR) glasses that overlay computer-generated elements with the real world. Although AR ...

Nano-magnets produce 3-D images

Conventional 3D displays, such as stereo displays with glasses and glass-free autostereoscopic displays, show two-dimensional images for each eye. Therefore, users experience incongruity and eyestrain owing to these pseudo-3D ...

Shrinking 3D technology for comfortable smart phone viewing

Imagine watching a 3D movie on your smart phone and suddenly getting a headache or even feeling nauseous. Such viewer discomfort is one of the biggest obstacles preventing widespread application of 3D display technology – ...

Creating high-resolution full-color moving holograms in 3-D

Three-dimensional (3D) movies, which require viewers to wear stereoscopic glasses, have become very popular in recent years. However, the 3D effect produced by the glasses cannot provide perfect depth cues. Furthermore, it ...

Glasses-free ultrahigh-definition 2D/3D switching display

Toshiba Corporation has developed a new technology for glasses-free 3D displays that uses a low-crosstalk, high-definition LCD GRIN lens with a 15-inch 4K LCD panel. The technology realizes a highly portable, compact display ...
