Each day seems to bring another announcement of an imaging technology breakthrough. Today's news comes from the Chicago Tribune, which reports that researchers at the University of Illinois at Urbana-Champaign and Northwestern University have invented a new digital sensor that mimics the human eye. And that is the Holy Grail of camera technology.
The new sensor collects light on a curved surface resembling a retina, rather than on the flat surfaces of sensors in most digital cameras. The engineers say the curved surface reduces the need for multiple lenses to focus light on the sensor and so cuts down on distortion. The work was described in the new issue of the journal Nature.
There are other implications for the work, as well, such as one day inventing actual bionic eyes. This breakthrough might really be worth it.—David Schonauer
