Recent experiments have confirmed that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the 3D shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (…

Crash-test dummies, yarn-spinning machines, and steel girders in bridges. What do they have in common? Look inside them all and you find transducers, devices that measure the forces that push, pull, weigh upon, and slam into them. But transducers also have something in common: Until recently, it…

'Pssst! Hey kid, ya wanna be a metrologist?"..."Uh, what's a metrologist?"... "Ya get paid to measure stuff."..."Sounds kinda boring." So it goes at colleges and universities all across the United States.
The fields of science, technology, engineering, and mathematics—collectively known as STEM—…
The use of optical 3D shape measurement devices are rapidly gaining importance, allowing the reconstruction of real 3D objects efficiently. The 3D shape and texture can be obtained from stereo images acquired with a freely moving camera. This approach measures the image displacement from the…

“So what’s the weather gonna do today?” I am sure that we have all been asked that after answering the first question (about what we do for a living) with: “Metrology.”
Metrology or meteorology? Both are studies of a particular science but are two words that are easily mistaken or misinterpreted…

Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 km) on either side of the planetary…

Materials that are firmly bonded together with epoxy and other tough adhesives are ubiquitous in modern life—from crowns on teeth to modern composites used in construction. Yet it has proved remarkably difficult to study how these bonds fracture and fail, and how to make them more resistant to…
NIST
To support the fair sale of gaseous hydrogen as a vehicle fuel, researchers at the National Institute of Standards and Technology (NIST) have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for…

For decades now, the measurement systems analysis (MSA) approach has been the predominant method for evaluating measurement systems capability. Although this method is widely considered to be an acceptable and comprehensive approach throughout most of the world, a growing number of specialized…

I started out my day with a quick chat with a colleague about a client project she is working on. It concerns calibration, and I could hear the tone of a righteous lecturer creeping into my voice.
After a very long career in quality, I realize there are certain subjects that really get my blood…

What happened to the good old show-me-the-money capitalistic down-and-dirty business I grew up with? Where’s the cutthroat competition? What happened to “we’re big, you’re not, we’re doing it our way” partnerships?
Something happened when I was wasn’t looking because business is all so touchy-…
Most of us, at one point or another, have been faced with making a decision to purchase a software application. Whether a simple application to manage your schedule or a more complex quality management software, the challenge is the same: How do you decide if a software application meets your…

What do you do when 20 ultra-rare violins from the 1730s show up in town, ready to be measured? Further, what exactly would you want to learn from these measurements? For many of us, the first thing that jumps to mind is, “Why do these particular instruments sound so much better than others of…

The Oasis of the Seas is the largest passenger ship in the world with a gross tonnage of 225,282 and room for more than 5,400 passengers. Not surprising, it creates a huge bow wave when sailing the seas and encounters waves of more than 60 ft when crossing the Atlantic Ocean.
When wave action…

With the 30th anniversary of the Coordinate Metrology Systems Conference (CMSC) around the corner, I am happy to celebrate World Metrology Week with you. This year’s conference will be held in North Charleston, South Carolina, from July 21–25, 2014. Charleston is the oldest and second-largest city…
Laser trackers and the software that controls them have revolutionized the way metrology data have been taken. With software and hardware advances have come new and better ways to take measurements. One of these advances in metrology software is the ability to measure the angle normal to a mirrored…
