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 ...

Researchers have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest ...

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 rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS devices typically have actively moving ...
