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 ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

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 ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

A team of scientists has managed to successfully perform atom interferometry in space - on board a sounding rocket. Extremely precise measurements are possible using atom interferometers that employ ...
