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 MediaARTICLESImager Could Help Autonomous Vehicles See Around CornersAn around-the-corner camera system built by engineers at Stanford University uses a wave-based image formation model to allow non-line-of-sight (NLOS) imaging.
