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 ...

Albert Michaelson demonstrated the first interferometer in the 1880s, using a beam splitter and two mirrors. The core principles remain the same in interferometers used today.

Interferometers exploit the wave-like nature of a beam of light. The beam is split and sent down two separate paths, where the beams bounce off mirrors to return to the beam splitter to be recombined.

An offshoot of interferometry, called the Lyot test (I think), has been used to test optics. If memory serves, a phase shift is introduced in part of the beam.

A super compact interferometer developed by the lab of Chunlei Guo, professor of optics at the University of Rochester, will give scientists an unprecedented ability to fine tune even the quickest ...

All interferometers consist of the same general components. A light source emits a beam that is separated into test and reference beams at a beam splitter. These two beams further propagate and are ...

Matter-wave interferometry can be used to probe the foundations of physics and to enable precise measurements of particle properties and fundamental constants. It relies on beam splitters that ...

The classical optical interferometer setup comprises a laser that shines a beam of light through a beam splitter. One light wave travels down the vertical arm, and the other travels down the ...

To illustrate the quantum mechanical principle of complementarity, Bohr1 described an interferometer with a microscopic slit that records the particle's path. Recoil of the quantum slit causes it ...
