CAMBRIDGE, Mass., Dec. 28, 2017 — In a novel approach to time-of-flight (ToF) imaging, researchers correlated the principle of heterodyning to ToF, increasing depth resolution 1000-fold. Higher ToF resolution could enable accurate distance measurements through fog, removing a major obstacle to the development of self-driving cars. At a range of 2 m, existing ToF systems have a depth resolution of about 1 cm. In contrast, a new ToF system developed by a team at MIT has a depth resolution of 3 µm at distances of 2 m. MIT researchers present a new scheme of heterodyne lidar that uses a cascaded stack of...Read full articleRelated content from Photonics MediaARTICLES3D Imaging Sees Growth in Multiple DimensionsFrom time to time, we all find ourselves forced to rummage through the cluttered jumble of our home “junk drawer” to dig out a screwdriver, battery, paper clip, or other much-needed...Vision Spectra Summer 2021 IssueOn-Chip Deep Neural Network Detects and Classifies Images in an InstantAn optical deep neural network integrated on a chip could be a significant advancement for image classification technology.
