Nanowire lens can reconfigure its imaging properties
No need for color correction: Perfect colors, captured with one ultra-thin lens
Most lenses are, by definition, curved. After all, they are named for their resemblance to lentils, and a glass lens made flat is just a window with no special powers. But a new type of lens created at the ...
Distant supernova split four ways by gravitational lens
Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes.
Thermal vision: Graphene light detector first to span infrared spectrum
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens.
Google contact lens could be option for diabetics
Brian Otis gingerly holds what looks like a typical contact lens on his index finger. Look closer. Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. ...
Integral 3D TV system projects a promising future (w/ Video)
Nanodiamond-embedded contact lenses may improve glaucoma treatment
(Phys.org) —By 2020, nearly 80 million people are expected to have glaucoma, a disorder of the eye that, if left untreated, can damage the optic nerve and eventually lead to blindness.
Device turns flat surface into spherical antenna
By depositing an array of tiny, metallic, U-shaped structures onto a dielectric material, a team of researchers in China has created a new artificial surface that can bend and focus electromagnetic waves ...
Contact lens merges plastics and active electronics via 3-D printing
(Phys.org) —As part of a project demonstrating new 3-D printing techniques, Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens, allowing the device to project beams ...
Lens combines human and insect vision to focus wide-angle views
A lens invented at The Ohio State University combines the focusing ability of a human eye with the wide-angle view of an insect eye to capture images with depth.
Researchers create lens to turn smartphone into microscope
Researchers at the University of Houston have created an optical lens that can be placed on an inexpensive smartphone to magnify images by a magnitude of 120, all for just 3 cents a lens.
A breakthrough in superlens development: Cheap, simple lens to let us see a single virus
A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in ...
Telescopic contact lens could improve eyesight for the visually impaired
(Phys.org) —A team of engineers has designed a telescopic contact lens that can switch between normal and magnified vision by using slightly modified off-the-shelf 3D television glasses. The researchers, ...
Multiview 3-D photography made simple
Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can.
