Bamboozling Photons with a ‘Synthetic’ Magnetic Field EXETER, England, Sept. 17, 2020 — Researchers at the University of Exeter have developed a way to manipulate light with a “synthetic” Lorentz force — which is responsible in nature for a number of phenomena such as the aurora borealis. The technique allows the...
Quantum Light Squeezes Out Noise OAK RIDGE, Tenn., Sept. 16, 2020 — Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) used quantum optics to advance state-of-the-art microscopy and, in doing so, chart a a path to detecting material properties with greater sensitivity than is...
Researchers Look to Combine AI and IR Sensing to Save Lives STANFORD, Calif., Sept. 16, 2020 — Researchers at Stanford University are looking at AI and infrared sensing to save lives in smart hospitals and at-home care, specifically in a study that looks at 170 scientific papers to gather information on the field of “ambient...
Lidar System Delivers Vision Through Clouds and Fog STANFORD, Calif., Sept. 15, 2020 — Using a single-photon avalanche diode that can detect the arrival times of photons down to a single photon, with precision in the tens of trillions of seconds, researchers at Stanford University have developed a lidar system capable of seeing...
Primary Mirror Completed for NASA’s Roman Space Telescope GREENBELT, Md., Sept. 15, 2020 — The Nancy Grace Roman Space Telescope’s primary mirror has been completed, NASA announced. The telescope will have a field of view 100× greater than the Hubble Space Telescope, and it will use infrared light to study hidden structures....
Microwave Photonic Filters Reconfigured Without an External Device LAUSANNE, Switzerland, Sept. 14, 2020 — Researchers from École Polytechnique Fédérale de Lausanne’s (EPFL) have developed a method of reconfiguring microwave photonic filters without the need for an external device. The research may enable more compact,...
OCT Technique Offers High Speed, High Resolution SEATTLE, Sept. 14, 2020 — Researchers at the University of Washington have modified the standard process of OCT (optical coherence tomography) to detect minute changes in response to light in individual photoreceptors in the living eye. The technique has potential in the...
