It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...
The new INTERFEROMETER VI-direct SLP represents a cost effective phase shifting interferometer. Equipped with a high resolution camera, phase shifting unit and stabilized HeNe laser, the ...
Nanopositioning specialist Queensgate and the UK’s National Physical Laboratory (NPL) have forged a productive collaboration yielding a good-practice implementation model for Queensgate’s in-house ...
An experiment by a team of researchers led from the University of Waterloo's Institute for Quantum Computing shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum, can ...
The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence ...

Physicists outline first test to actively steer gravitational waves
Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely ...
A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...
Rochester, New York–The Melles Griot Optics Group today announced that they have released additional Fizeau interferometer test optics to complement their Absolute™ Fizeau l/40 transmission sphere ...
Arvix paper contends the spacetime distortions resulting from the experimentally obtainable electric field of a parallel plate capacitor configuration cannot be detected by the White-Juday Warp Field ...
