Future VR headsets could use a new type of lens inspired by holographic devices. The bilayer bifocal lens relies on external ...

Scientists have created a compact spectral singlet lens that turns standard cameras into hyperspectral ones, reducing system ...

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 ...

The traditional “spectrometer + lens” setups in hyperspectral cameras involve performance tradeoffs when the system is driven ...

Liquid crystals exist in a phase of their own. They can flow like liquids, but because their molecules are arranged in a somewhat orderly way, they can be easily manipulated to reflect light.

One notable class of these materials is lyotropic chromonic liquid crystals (LCLCs), which are molecular assemblies of amphiphilic π-electronic molecules, with water-absorbing and water-repelling ...
