PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares
A PML team is hitting the road with a fine-tooth comb. Scientists in the Quantum Electronics and Photonics Division have devised a portable optical frequency
Commentary by Mark Esser. Every year, we hear scattered stories of inaccurate measures. Gas pumps, grocery scales, grocery scanners, incorrectly labeled
A team of PML scientists and collaborators* has achieved a five-fold reduction in the dominant uncertainty in an experiment that measured the mean lifetime of
It might seem that when the world agrees on a new definition of the kilogram based on a fixed value of a physical constant, as is expected soon, no one will
Piezoelectrics—materials that can change mechanical stress to electricity and back again—are everywhere in modern life. Computer hard drives. Loud speakers
Tiny, self-powered sensors that can be embedded in bridge structures and networked wirelessly to continuously monitor the structure's health. Little fly-by-wire
Laser trackers are state-of-the-art measuring machines that are capable of measuring the dimensions of large objects (up to approximately 120 meters in length)
After two years of difficult and meticulous work examining, refurbishing, and testing the aging workhorse watt balance called NIST-3, PML researchers have used
