The MSC WLI white-light interferometer measures surface parameters such as profile, roughness, step height, and microstructure without damaging the target. Its light source is a high-brightness LED ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

A lot of what I write is about measurement, not because I’m in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

Extremely precise measurements are possible using atom interferometers that employ the wave character of atoms for this purpose. They can thus be used, for example, to measure the gravitational field ...
