Sandia National Laboratories
Sandia’s Engineering Sciences Center helped mark National Engineers Week with a contest, asking Sandians to complete the following sentence: “You know you’re an engineer when… .” The contest drew dozens of endings for the sentence, and Sandians voted on which they liked best.
Barbara Lewis won…

Happy belated Pi Day! No, not pie day, Pi Day, which was last week. Pi is that Greek character you’ve heard of but aren’t quite sure what the big deal is. Pi is the ratio of a circle’s circumference to its diameter. As yawn-inducing as that may sound, it’s an important ratio because pi is the same…

Medical implants and spacecraft can suddenly go dead, often for the same reason: cracks in ceramic capacitors, which are devices that store electric charge in electronic circuits. These cracks, at first harmless and often hidden, can start conducting electricity, depleting batteries or shorting…

As happened with most every metrologist I know, I fell into metrology (the science of measurement) quite by accident. My degree was in chemical engineering, and I was probing the world around me to see what kind of work was out there for someone with my skills and interests. I learned of an…

NIST scientists have devised and improved a prototype instrument the size of a loaf of bread that can substantially increase the accuracy of length measurements in commerce. Perhaps surprisingly, it does so by achieving the most accurate measure of the refractive index of air reported to date.
An…

Like many of you, I venture out on Saturday mornings to get groceries and gas. Until my college years, I never thought much about whether or not I paid the right amount at the pump, if the supermarket scale was correct, or if packaged foods actually contained the amount of product stated on the…

The nefarious Major Uncertainty has kidnapped Monsieur Kilogram, putting the world’s measurements of mass in jeopardy. As the world spirals into “Mass Hysteria,” the remaining SI Superheroes, champions of the metric system, leap into action to save the day, and hopefully Monsieur Kilogram as well…

It is my pleasure to welcome you to this issue of CMSC World. Our 3D metrology community is small compared to the bigger circles of civil engineering, manufacturing engineering, or even quality engineering. An even scarcer sight is a female 3D industrial metrologist, such as me.
It has been and…

I n this article, we present a wide angle, frequency scanning interferometer (FSI) system capable of measuring the absolute distance to multiple targets simultaneously.
A spatial light modulator has been integrated into the FSI sensor head, projecting multiple beams towards targets. Absolute…

Let’s say you’re a biotechnologist working to develop new medicines or a better test for forensic analysis. You might find yourself frequently using absorbance spectroscopy, a technique that allows researchers to identify even small amounts of a substance (such as DNA) or an antibody based on how…

Physicists at NIST’s Physical Measurement Laboratory (PML) have been working on a new class of chip-based photonic thermometers that measure temperature with light. Now the team has reached another key milestone with the creation of a system that tests and packages their photonic thermometers…

As a physicist who explores ways to measure light more accurately, it should come as no surprise that I’m fascinated by even common optical phenomena that we see all around us (e.g., rainbows or oil slicks on butterfly wings).
Rainbows occur because light travels through water and air at…

A collaboration between NIST researchers and a private-sector firm has led to the development of a commercial device to fill a critical need in industry: calibration of laser tracking systems.
Laser trackers are state-of-the-art instruments capable of measuring the dimensions of objects as large…

All machine tools need maintenance, adjustment, and calibration over time. For precision multi-axis machines, scheduled service including machine conditions, performance, and calibration are necessary to maintain machine performance, thereby reducing scrap or rework. Regular calibration is also a…

In a world of incessant change, some things have to stay the same. One is the set of values for the fundamental physical constants—such as the speed of light or the charge of the electron—that underlie precision measurements in industry, science, and medicine worldwide.
Yet even the constants…

To reduce weight and fuel consumption, the aerospace industry increasingly relies on lightweight materials and new material combinations. That’s why the entire fuselage of the Airbus A350 XWB consists of carbon fiber composite (CFC) materials. In total, the long-haul aircraft reaches a CFC portion…
