Sub-RF Imaging Advanced by Lasers
GAITHERSBURG, Md., and ANN ARBOR, Mich., June 18, 2014 — Laser-enhanced radio frequency mapping could lead to better assessment of the properties of metasurfaces. Traditional field mapping requires the use of millimeter-scale antennas and dipoles, similar in size to the radio frequencies they measure. This poses practical limitations on the smallest features that can be measured. A technique developed by a team from the National Institute of Standards and Technology and University of Michigan overcomes these limitations using laser light
Nanowire Probes Provide Visual Enhancement for AFM
GAITHERSBURG, Md., May 28, 2014 — Nanowire probe tips originally intended for atomic force microscopes in near-field scanning microwave microscopy (NSMM) applications could have another use.
NIST Awards Advanced Manufacturing Grants
GAITHERSBURG, Md., May 9, 2014 — GAITHERSBURG, Md., May 9, 2014 — Two projects aimed at advancing photonics manufacturing have been awarded grants from the National Institute of Standards and Technology (NIST) through its Advanced Manufacturing Technology Consortia (AMTech)...
Bug Sensors Could Slow Infection, Defend Crops
RIVERSIDE, Calif. and SAO PAULO, Brazil, May 1, 2014 — Better classification of insects in the wild could be a key to protecting crops and halting the spread of diseases. A team from the University of California, Riverside, in collaboration with the University of Sao Paulo and ISCA Technologies, has...
American Laser Society Names New President
WAUSAU, Wis., April 17, 2014 — The American Society for Laser Medicine and Surgery has named Dr. Juanita J. Anders its new president. Under her leadership over the next year, the organization says it plans to increase interaction and cooperation of scientists, innovators and...
Diffractive Catheter Enhances OCT Imaging
BALTIMORE and SEATTLE, March 12, 2014 — A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption.
Lasers and Fake Corneas Connect Teens, STEM and Photonics
Mar 7, 2014 — Learning middle school science from a textbook can be boring; at least it was for me! But it would have been less so if I could have constructed solar ovens, performed “simulated laser surgery” or seen photonic technologies at work in...
Space Lasers Have ‘Bright Future’ in Communications
GREENBELT, Md., Dec. 30, 2013 — Neither wind, nor clouds, nor even atmospheric turbulence kept NASA’s Lunar Laser Communication Demonstration (LLCD) from its mission of providing error-free communications to ground stations from lunar orbit, NASA said recently in releasing...
Optics Expert Garners Chief Scientist Post at ARL
ADELPHI, Md., Dec. 20, 2013 — Dr. Joseph Mait, a fellow of both the Optical Society (OSA) and SPIE, was recently named chief scientist of the US Army Research Lab (ARL). Mait has worked at ARL since 1988 in various roles, including group leader for basic research in optics and...
Hubble Spots Vapor Venting Off Europa
GREENBELT, Md., Dec. 18, 2013 — NASA’s Hubble Space Telescope spectroscopically detected water vapor over the frigid south pole of Jupiter’s satellite Europa, providing the first strong evidence of water plumes erupting off the moon’s surface. This is an...
Laser-Based Communications Passes Military Tests
CLIFTON, N.J., Nov. 26, 2013 — A monthlong evaluation of a high-speed, laser-based communications system funded by the Office of Naval Research was successfully tested by Exelis and its partner, the company said this week. Aerospace and defense communications and information...
Geodesy Applications Pursued for Atom Optics
GREENBELT, Md., Nov. 12, 2013 — An atom interferometer under development to measure gravitational ripples in space-time with picometer-level sensitivity could also advance geodesy, the science of measuring the Earth’s size, shape and gravitational field. Technologists...
Laser Mapping of Greenland’s Summer Ice Melt Begins
THULE, Greenland, and GREENBELT, Md., Nov. 6, 2013 — For the first time, NASA is laser-mapping changes to the Greenland Ice Sheet produced by a single season of summer melt. The data gathered will provide a more comprehensive view of season changes and provide context for a more ambitious mapping...
Atomic clocks set stability record
GAITHERSBURG, Md. – A pair of experimental atomic clocks based on ytterbium atoms at NIST has set a record for stability. Acting like 21st-century pendulums, the clocks have perfect timing and could potentially swing back and forth with precise ticks for a period...
Sunshield for NASA Telescope Ready for Manufacturing
REDONDO BEACH, Calif., Sept. 27, 2013 — The template layers of a tennis-court sized sunshield that will help protect the optics on NASA’s James Webb Space Telescope have been completed, marking the final step before the final flight sunshield will be manufactured. Project...
Microscopy technique could help make 3-D components
GAITHERSBURG, Md. – A technique developed several years ago to improve optical microscopes has now been applied to monitoring the next generation of computer chip circuit components, providing a crucial tool for developing 3-D components. Through-focus scanning optical...
New photodetector makes do with few photons
COLLEGE PARK, Md. – The fundamental probabilistic nature of light makes it impossible to perfectly distinguish light from dark at very low intensity. Low power and high fidelity in reading data are especially important for secure communications and quantum computation;...
Atomic Clocks Set Stability Record
GAITHERSBURG, Md., Aug. 23, 2013 — At the National Institute of Standards and Technology (NIST), a pair of experimental atomic clocks based on ytterbium atoms has set a new record for stability. Acting like 21st-century pendulums, the clocks have perfect timing and could,...
Electronic components speed spectroscopy
GAITHERSBURG, Md. – Using electronic components could make atmospheric-gas measurement more even and 1000 times faster than with conventional techniques, and could advance greenhouse-gas measurement. Spectroscopy is the most common method for detecting trace gases....
Lockheed updates laser rangefinders
Aug 1, 2013 — Lockheed Martin of Bethesda, Md., has delivered the first modernized day sensor assembly (M-DSA) laser rangefinder designator (LRFD) for use on the US Army’s AH-64D Apache helicopter. As the chief targeting aid for the Apache, the LRFD is...
Spray-on flat lens works in the UV
GAITHERSBURG, Md. – A new, easily fabricated metamaterial-based flat lens that bends and focuses UV light could improve photolithography, nanoscale manipulation and manufacturing, and even high-resolution 3-D imaging, say its developers, scientists working at the...
Another Milestone for Optics Engineer’s Superblack Material
GREENBELT, Md., July 18, 2013 — A superblack carbon-nanotube technology developed five years ago has achieved another milestone, and this time it promises to make spacecraft instruments more sensitive without enlarging their size.
New Nanoimaging Method Finds App in Plasmonics
GAITHERSBURG, Md., July 17, 2013 — Theoretical calculations to understand and predict the optical properties of plasmonic nanomaterials exist but haven’t been verified in the lab, until now.
