Artificial eyeball does away with distorted images

By assembling an array of photodiodes bound flexibly with wire, researchers have managed to create curved image sensors that mimic a biological retina (Image: University of Illinois) news service, Aug 6, 2008
University of Illinois at Urbana-Champagne researchers have built a hemispherical digital-image sensor that can take wide-angle pictures without distortion by mimicking the curves of a human retina.
They attached an array of silicon photodiodes on a curved "retina."
The technology may make it possible to give the curved surface of a human retina a coat of digital sensors, helping blind people see again.
