Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

Realization of color filter-free image sensors

A South Korean research team has developed an image sensor that captures vivid colors without color filters. The Korea Research Foundation announced that Professor Dae Sung Chung (Daegu Gyeongbuk Institute of Science and ...

Researchers offer new technology for liquid-crystal displays

An international research team from Russia, France and Germany has proposed a new method for orienting liquid crystals. It could be used to increase the viewing angle of liquid-crystal displays. The paper was published in ...

Image: The moon in 1992

The moon was a focal point for NASA in 2017, whether it was blocking out the sun during one of the most-viewed events in U.S. history, or reinvigorating the agency's human space exploration plans. But the moon has always ...

Rosetta: OSIRIS detects hints of ice in the comet's neck

The Hapi region on the neck of Rosetta's comet 67P/Churyumov-Gerasimenko reflects red light less effectively than most other regions on the comet. It thus appears slightly blueish. The Hapi region is located between the comet's ...
