We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...

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 ...

A super compact interferometer will give scientists an unprecedented ability to fine tune even the quickest pulses of light for a host of applications, and could render traditional instruments for ...

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 ...

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

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 ...

This release is also available in German. Due to their stable design, Fizeau interferometers are used to determine the topography of surfaces such as, e.g., plane surfaces. PTB has now developed a ...

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.
