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
As mechanical objects, gears have been around for so long that people may take them for granted. But gears are sophisticated parts that play a vital role in
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
Deposition of carbonaceous material under electron beam irradiation is an old and persistent problem of scanning electron microscopy. It is an impediment to

Background: The industry is developing extreme-ultraviolet wavelength (EUV) techniques to measure critical dimensions (CDs) in logic fabrication. As nascent
In semiconductor device manufacturing, 3D structure measurements of newly complex devices would be valuable alongside conventional scanning electron microscopy

We describe a method to calibrate angular positioning errors of a rotation stage using a laser tracker (LT), a plane mirror mounted on the stage, and stationary
Since 2006, the Nanomechanical Properties Group has pioneered the use of Laser Doppler Vibrometry (LDV) to calibrate the stiffness of AFM cantilevers using the
