Researchers at the National Institute of Standards and Technology (NIST) have been developing a novel way of measuring laser power. Their device, called the Radiation Pressure Power Meter (RPPM), makes its measurements using the force exerted by the laser light itself.

During the May 18, 2018, episode of QDL, we had a terrific conversation with Gary Confalone of the Coordinate Metrology Society, and also considered the importance of mindfulness and good manners in life and work. Let’s take a look:

In our May 11, 2018, episode of QDL, we looked at overproducing ideas, bad quotas (aren’t they all), and how anger can help identify core values.

“Questioning Quotas”

When are quotas bad? Most of the time. But here’s a good example.

Historical dimensions for the cubit are provided by scripture and pyramid documentation. Additional dimensions from the Middle East are found in other early documents. Two major dimensions emerge from a history of the cubit. The first is the anthropological or short cubit, and the second is the architectural or long cubit.

Laser trackers are widely used for metrology and precision surveys. Depending on the approach, range, and instrument itself, the measurement accuracy can vary from millimeter to micron. Several applications of laser trackers used in the National Synchrotron Light Source II (NSLS-II) project will be explained in this article to show examples of using laser trackers to achieve very high accuracy.

You run a manufacturing business, so you know how it goes. The cost of doing business and manufacturing product never decreases. You know that your revenue must increase just to keep up. You also know that merely maintaining your revenue status quo will only ensure you get your lunch eaten by inflation. Or by your competition. If you aren’t growing your profits, you aren’t just standing still—you’re going backward. There is no such thing as “flat growth.” If your company’s revenue is not increasing year over year; it’s dying a slow death.

Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a smooth surface of the same object.

Modern 3D laser confocal scanning microscopes can resolve fine surface-topography detail as minute as a few nanometers, quickly and easily. It is the solution that advanced manufacturing industries turn to for efficient quality assurance surface inspections.

You can’t see well without lenses that can focus, whether those lenses are in your eye or the microscope you peer through. An innovative way to focus beams of neutrons might allow scientists to probe the interiors of opaque objects at a size range they were blind to previously, allowing them to explore the innards of objects from meteorites to cutting-edge manufactured materials without damaging them.

Invented in 1987 and commercially available since 1991, laser trackers have long been a mainstay of the aerospace industry. Automotive manufacturers have also adopted laser trackers for quality control (QC) and design. The fact is, any industry dealing with large-scale measurements—from small machine shops to medium-sized enterprises to major Tier 1 automotive and aerospace suppliers—all share the potential to realize tremendous benefits by adopting laser tracker technology.
