For several years, a team of researchers from the National Institute of Standards and Technology (NIST) has been building a robotically operated moonlight
Frequency combs — specialized lasers that act like rulers to measure light — are now being brought down to a low-power, chip-scale form. NIST researchers David
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
Building on a successful first-year Strategic and Emerging Research Initiatives (SERI) project NIST and Autonomous Vehicles (see 2022 NIST AV workshop and
Photographs, or optical light images, are spatial records of light reflected or emitted from objects. Thus, they are prospective light measurements. In many
NIST cooperates with the three services (Air Force, Navy, and Army) to realize a uniform night vision goggle (NVG) calibration system with low measurement
