A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

How innovations in visibility, usability, and smart sensing are changing who uses tools—and how. For centuries, measurement tools have been essential to architecture, engineering, construction, real ...

Sometimes you absolutely, positively need to know the angle of the cutting edge on a knife. When you do, the best tool for the job is a laser goniometer, and [Felix Immler] shows us three different ...

Laser interferometry has emerged as a leading non‐contact method for the precision measurement of gear geometries. By utilising the interference of coherent light, these systems can detect minute ...
