DURHAM, N.C. - Engineers at Duke University are leading a nationwide effort to develop a camera that takes pictures worth not just a thousand words, but an entire encyclopedia.
Funded by a five-year, $7.5 million grant through the Department of Defense s Multidisciplinary University Research Initiative (MURI) competition, the team will develop a super camera that captures just about every type of information that light can carry, such as polarization, depth, phase, coherence and incidence angle. The new camera will also use edge computing and hardware acceleration technologies to process the vast amount of information it captures within the device in real-time.

Polished glass has always been the cornerstone of modern optics and imaging systems. Shaped precisely, it helps us focus light and produce sharp images. However, changing its focus requires physically tilting, sliding, or shifting the lens, often mechanically, which adds bulk to microscopes and telescopes. It is also hard to miniaturize the classical lenses and mirrors currently used.
Metalens technology could solve this problem by exploiting light and matter interactions at the nanometer scale to achieve unparalleled control of light s behavior.
Metalenses are flat surfaces etched with nanostructures that manipulate and focus light. They possess unique properties that cannot be achieved with conventional diffractive surfaces. Furthermore, they are thin, easy to make, and cost-effective.

Cambridge, Mass. – February 4, 2021 – A startup company founded by applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) intends to transform consumer electronics by introducing a powerful technology for imaging and illumination that could replace conventional lenses with an ultrathin, flat optical microchip.
Harvard’s Office of Technology Development (OTD), which cultivates the University’s industrial research collaborations and oversees technology commercialization, has granted Boston-based Metalenz, Inc. an exclusive, worldwide license to a portfolio of innovations in flat optics developed in the Harvard lab of Federico Capasso. Metalenz made its plans public today and announced $10 million in investment from Intel Capital, 3M Ventures, Applied Ventures, and TDK Venture
