When astronomers talk about an optical telescope, they often mention the size of its mirror. That's because the larger your mirror, the sharper your view of the heavens can be. It's known as resolving ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring minute ...

A new technique in matter-wave interferometry using laser light to fragment molecules may open the door to interference demonstrations with large bio-molecules or nanoclusters. Figure 1: In the ...

An atom interferometer embedded in an optical cavity requires less power compared to previous techniques and may work with a wider variety of atoms and molecules. Atom interferometry, in which atomic ...

“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 ...

The ESO (European Southern Observatory) has announced the successful observation of an exoplanet using optical interferometry. It's the first time an exoplanet has been "seen" in this manner and the ...

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

Modern semiconductor manufacturing technology has advanced rapidly. Because of this, measurement using non-contact displacement and transparent coating thickness has become very critical. Applications ...
