Fibers Could Replace Camera Lenses
Picture a wall that stares back at you. Or a uniform that shows a soldier a 360-degree view of the battlefield. Both scenarios are possible courtesy of a new generation of flexible, translucent fibers developed by researchers at the Massachusetts Institute of Technology (MIT) in Cambridge. These so-called multimaterial fibers can turn incoming light waves into images without the need for a camera lens. And unlike fiber optic cables, they can transmit images that have been captured across their entire length.

The multimaterial fibers developed by the MIT team could solve this problem and provide a host of other benefits. The fibers consist of an array of metal electrodes connected to a semiconductor and are covered by an insulating polymer sheath. The semiconductor layer in the fiber detects light and relays signals via the electrodes to a microprocessor, which combines the signals from an array of the fibers to determine the light's intensity, direction, and color. Visualization software then takes that data and recreates the source image and displays it on a monitor screen. And the whole process is accomplished without a lens.
