A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

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

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 ...

An international research team led by Gerd Weigelt from the Max-Planck-Institut fuer Radioastronomie in Bonn reports on high-resolution studies of an active galactic nucleus in the near-infrared. The ...
