Having such precise models of lunar dust will enable NASA and private space exploration companies to create more accurate simulations of the Moon’s surface.
For more than three decades, the National Institute of Standards and Technology (NIST) has calibrated the wavelengths of lasers used in industry, academia, and...
New dimensional measurement technologies provide significant benefits to industry such as increasing measurement throughput, enabling new manufacturing process and providing more detailed part information for manufacturing process improvement. However, before purchasing and using new measurement...
Diffraction techniques can provide data on a number of sample characteristics. Therefore, the method of certification and the artifact itself are chosen to address a specific measurement issue pertinent to a diffraction experiment. NIST diffraction SRMs may be divided into five groups: Line Position...
The Dimensional Measurement Services project promotes manufacturing innovation and U.S. industrial competitiveness by providing critical technology-enabling high accuracy dimensional measurements within an internationally accepted quality system. These measurements span the dimensional metrology...
Objective
To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological...

Decay energy spectroscopy relies on the absorber, a small substrate where the radioisotopes are embedded and thermalized, for high counting efficiency and...
Two-color refractivity measurements are reported for carbon dioxide, oxygen, binary mixtures of nitrogen--oxygen, natural dry air, and water vapor. For the '...
NIST is developing a suite of material metrology tools to understand and characterize the development of residual stresses during epoxy curing. In this work...
Over 10 independent digital image correlation (DIC) measurement systems are available in the NIST Center for Automotive Lightweighting. The majority of these
Since 2006, the Nanomechanical Properties Group has pioneered the use of Laser Doppler Vibrometry (LDV) to calibrate the stiffness of AFM cantilevers using the
