CAMBRIDGE, Mass., Dec. 2, 2015 — The resolution of conventional 3D imaging devices can be increased by as much as 1,000 times by exploiting the polarization of light. That's the conclusion of an international team of researchers who modified a Microsoft Kinect time-of-flight sensor with a polarizing filter. Their device, called Polarized 3D, yielded feature resolution in the hundreds of microns at a distance of several meters. On its own, the Kinect achieved centimeter-scale resolution. By combining information from a Microsoft Kinect depth frame (a) with polarized photographs, MIT researchers reconstructed...Read full articleRelated content from Photonics MediaARTICLESScalable Approach to Lidar Could Propel Autonomous Vehicles, Other TechA silicon chip with a serpentine optical phased array (SOPA), developed by researchers at the University of Colorado Boulder, could improve the resolution and scanning speed of lidar systems while...Vision Spectra Winter 2020 IssueResearchers Fool Autonomous Vehicles to Pinpoint Security RisksTests showed that an attack strategy demonstrated by Duke University researchers fooled industry-standard autonomous vehicle sensors into believing nearby objects are closer and/or farther than they...Photonics.com 3/30/2022Metasurface Tech Enables Polarization Imaging on Almost Any CameraResearchers from the Harvard John A.
