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.
