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 ...

Before an ESA mission reaches the launch pad, it has to go through a number of approval procedures that ensure the mission’s readiness. The future space-based gravitational wave observatory, the Laser ...

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 ...

Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.

Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ...

Building blocks: University of Nottingham researchers have developed a fully functional LEGO interferometer kit (courtesy: University of Nottingham) Working with “student LEGO enthusiasts”, they have ...

A novel calorimetric method has been developed for absolute determination of the spatial distribution of radiation absorbed dose in transparent liquids, particularly for dosimetry of pulsed, ...
