Anyone who's taken a picture of birthday candles being blown out or a selfie during a romantic candlelit dinner knows how disappointing it is when the photo comes out dark and grainy.
The engineering world just became even more colorful.
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 ...
(Phys.org) —Rice University researchers have created a CMOS-compatible, biomimetic color photodetector that directly responds to red, green and blue light in much the same way the human eye does.
(Phys.org) —TVs, image sensors, iPads, digital cameras and other modern devices use filters to display the breadth of colors available in the visible portion of the electromagnetic spectrum.
(Phys.org) —Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.
(PhysOrg.com) -- Engineers at Harvard have demonstrated a new kind of tunable color filter that uses optical nanoantennas to obtain precise control of color output.
(PhysOrg.com) -- A new kind of screen pixel doubles as a solar cell and could boost the energy efficiency of cell phones and e-readers. The technology could also potentially be used in larger displays to make energy-harvesting ...
