A graphene-based “beam splitter” for electronic currents has been built by researchers in France, South Korea, and Japan. Created by Preden Roulleau at the University of Paris and colleagues, the ...

If you want to get the greatest benefit from a beam of light - whether to detect a distant planet or remedy an aberration in the human eye - you need to be able to measure its beam front information.

A quantum trick based on interferometric measurements allows a team of researchers to detect even the smallest movements of a laser beam with extreme sensitivity.

According to Fermilab, the interferometer will occupy a 328 feet shaft at its facilities. This was used years ago for access ...

This is a preview. Log in through your library . Abstract X-ray free-electron lasers (FELs) deliver ultrabright X-ray pulses, but not the sequences of phase-coherent pulses required for time-domain ...

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 ...
