A micro-lens array with 50µm diameter lenses should settle in 1s, said Wu, and Fresnel lenses are though to be possible. If a polarisation-independent lens is required, the liquid crystal would have ...

The lens features a bilayer structure made of liquid crystal materials. Each layer responds differently to the applied electric field, splitting incoming light into oppositely polarized beams. Bifocal ...

The lenses, which use two layers of liquid crystal structures, could be useful for various applications such as optical interconnections, biological imaging, augmented/virtual reality devices and ...

Each "petal" of these flowers is a "focal conic domain," a structure that other researchers had shown could be used as a simple lens. "Given the liquid crystal flower's outward similarity to a ...

Since the lenses form spontaneously in liquid crystal, a medium that's easily reconfigured, it may be possible to create self healing re-configurable optical devices. And all that's just for starters.

Liquid crystal (LC) lenses with electrically tunable focal length have attracted much attention for their potential in ophthalmic applications, three-dimensional displays, cell phones, virtual reality ...

If you’re cursed with bifocals or fear they’re in your future, you’ll be glad to know optical scientists at the University of Arizona have been working on liquid-crystal eyeglass lenses that ...

In pursuit of this goal, one researcher at the University of Leeds is developing a unique, auto-focusing liquid crystal lens that may help cure age-related long-sightedness. Presbyopia ...

“A single glass lens has a chromatic aberration [it focuses different wavelengths at different distances]; this is also true, or even more significantly so, in the case of a pattern-alignment ...

A swipe on the frame sends an electrical signal to the two liquid crystal lenses to change the state of millions of tiny pixels so that close objects come into focus. As such, these 32 Degrees ...
