Liquid Crystal Compound Lens Eyed for 3-D Imaging

Facebook X LinkedIn Email
Liquid crystal can be controllably formed into compound lenses similar to those found in insects, a team from the University of Pennsylvania (Penn) has demonstrated. These lenses produce sets of images with different focal lengths, a property that could be used for 3-D imaging. They are also sensitive to the polarization of light, a quality thought to help bees navigate their environments. Previous work by the group had shown how smectic liquid crystal, a transparent, soap-like class of the material, naturally self-assembled into flower-like structures when placed around a central...Read full article

    liquid crystal
    Liquid crystals are a state of matter that exhibits properties intermediate between those of conventional liquids and solid crystals. In a liquid crystal, the molecules are ordered like those in a crystal, but they can still flow like a liquid. This unique combination of structural order and fluidity gives liquid crystals their distinctive characteristics and makes them valuable in various technological applications, particularly in display technology. Key features and characteristics of...
