Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...

Physicists have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms.

Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

Gravimetry, or the measurement of the strength of a gravitational field (or gravitational acceleration), has been of great interest to physicists since the 1600s. One of the most precise ways to ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using ...

Gravity is one of the more obvious forces in the universe, generally regarded as easily noticeable by the way apples fall from trees. However, the underlying mechanisms behind gravity are inordinately ...

“This three-telescope interferometry is a major milestone toward directly imaging the growth phase of supermassive black holes,” said Sebastian Hoenig, a postdoctoral researcher at the UC Santa ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

Zygo is a market leader when it comes to interferometric metrology instrumentation. With two key product lines in that category, Zygo offers an optical profiler and a laser interferometer as well as ...
