CAMBRIDGE, Mass., Feb. 5 -- A Massachusetts Institute of Technology (MIT) device that makes the world's most precise rulers -- with "ticks" only a few hundred billionths of a meter apart -- could impact fields from the manufacture of computer chips to space physics. The Nanoruler is 10 to 1000 times faster and more precise than other methods for patterning parallel lines and spaces (known collectively as gratings) across large surfaces more than 12 inches in diameter. Such large surfaces are key to a number of applications involving gratings, such as larger wafers for the production of...Read full articleRelated content from Photonics MediaArticlesMachine Learning Reduces Drift in Fiber SensorsUsing machine learning and an established mathematical model, scientists at the National Institute of Standards and Technology (NIST) developed a machine learning-based algorithm to predict drift in...Photonics Spectra January 2023 IssueLogistics, AI, and the Future of Work: An Interview with MIT’s Yossi SheffiYossi Sheffi, Ph.D., is the Elisha Gray II professor of engineering systems at the Massachusetts Institute of Technology where he serves as director of the MIT Center for Transportation.
