When we think of physics experiments, we tend to envision cavernous rooms filled with things like optical benches, huge coils in vacuum chambers, and rack after rack of amplifiers and data acquisition ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Cambridge Technology, based in Taunton in the United Kingdom, is a manufacturer of precision Beryllium mirrors. The company recently outlined how employing best-in-class interferometry hardware and ...

Focused Laser Differential Interferometry (FLDI) is an innovative, non‐intrusive optical diagnostic tool designed to capture high-resolution density fluctuations within hypersonic flow environments.

The European Space Agency (ESA) has launched the first payload of a mission designed to test optical hardware for detecting gravitational waves. The LISA Pathfinder mission, which blasted off from ...

Antonio García Marín and colleagues from the Albert Einstein Institute and University of Hanover describe the role that laser interferometry will play in the LISA and LISA Pathfinder missions (J. Phys ...

The Laser Interferometer Gravitational Wave Observatory (LIGO) detects the ripples in space-time by using a device called laser interferometer, in which the time it takes light to travel between ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely ...

"So far we have been watching the cosmos like a silent movie, capturing the ripples of spacetime with LISA will be a real game-changer, like when sound was added to motion pictures." When you purchase ...

The new LISA gravitational wave detector, which will be launched into orbit in 2035, promises to detect cosmic collisions from the earliest moments after the Big Bang. When you purchase through links ...
