Metrology

When manufacturing tolerances shrink to the micron, and part geometries become increasingly complex, the margin for measurement error disappears. In this space—where even thermal drift or mechanical vibration can invalidate results—motion control becomes not just a component but a cornerstone of…

A team from MIT Lincoln Laboratory has built and demonstrated wide-band selective propagation radar (WiSPR), a system capable of seeing out various distances at millimeter-wave (mmWave or MMW) frequencies. Typically, these high frequencies, which range from 30 to 300 gigahertz (GHz), are…

Imagine what life would be like without GPS, something you use all the time without thinking about where it came from.

NIST’s atomic clock research helped bring us GPS, which has had more than $1 trillion dollars in economic impact.

This is just one of the many scientific…

Robert “Bob” Hettich has spent much of his career at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) demonstrating how high-performance analytical measurements, in particular mass spectrometry, can yield remarkable insights into the mysteries of tiny microbes and their…

Ensuring that automotive components meet the highest quality standards is critical to vehicle safety and performance. Metals and protective coatings used in automotive manufacturing must withstand extreme conditions such as mechanical stresses, corrosion, and wear during a vehicle’s lifespan.…

Industrial hygiene equipment plays a critical role in ensuring workplace safety by monitoring airborne contaminants, noise levels, and other hazardous conditions. However, accurate readings depend on regular industrial hygiene equipment calibration to maintain precision and compliance with…
