Liquid Crystal Compound Lens Eyed for 3-D Imaging
PHILADELPHIA, May 21, 2015 — 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...
