Artificial vision gets resolution boost
7 April 2005

US scientists design an optoelectronic retina with 2500 pixels per millimeter.

An artificial vision system with a performance that is allegedly good enough to recognize faces, read large fonts and watch TV has been designed by a team of scientists at Stanford University in the US.

The system, described in the February 22 issue of Journal of Neural Engineering, features a wallet-sized computer, a tiny video camera mounted on a pair of goggles and an infrared-sensitive detector chip implanted in the retina. Tests are currently ongoing in rats and the retinal chips also about to be implanted into pigs. However, human trials are at least three years away.
