JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a metasurface attachment that can turn almost any camera or imaging system, even off-the-shelf systems, into polarization cameras. The technology developed in the Capasso Lab at Harvard could, in theory, establish a mechanism to turn a standard camera into a polarization camera, albeit without the capacity to identify material compositions. The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that...Read full articleRelated content from Photonics MediaArticlesLarge-scale, Mass-producible Metalens Enables Astral ImagingResearchers at the Harvard John A.
