BEIJING, Aug. 7 (Xinhuanet) -- U.S. researchers have
created the world's first "human eye" camera that could revolutionise
photography, according to meida reports Thursday.
The prototype device is about the same size and shape
as a real eye and has a curved "retina" that is sensitive to light.
Digital cameras work by focusing light onto a silicon
chip containing light-sensitive pixels. But expanding the field of view leads to
distortion around the edges. That's why vertebrate eyes are round -- to capture
more of a scene without losing clarity.
The bowl-shaped electronic "retina" made of silicon
could usher in a new generation of distortion-free digital and video cameras.
"This approach allows us to put electronics in places
where we couldn't before," said John Rogers, an engineer at the University of
Illinois, who led the research along with Yonggang Huang of Northwestern
University.
Experiments already under way are testing other potential
applications, including a thin, pliable monitor to detect electrical signals
travelling across the undulating surface of the human brain.
