It’s sometimes easy to forget that the light in the sky is an actual star. With how reliable it is and how busy we tend to be as humans, we can take that incredible fact and stow it away and largely ...

In 1989, the first Adaptive Optics prototype for ESO COME-ON with a 19 actuators deformable mirror had its first light in France before to be sent to La Silla. Following successful observing runs ...

For centuries, astronomers looking up at the heavens through a telescope had a problem on their hands – the quality of their images depended on the strength and direction of the wind in the air.

Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep ...

For astronomers, it’s a magical moment: you’re staring at a monitor, and a blurry image of a cosmological object sharpens up, revealing new details. We call this “closing the loop,” a reference to the ...

Adaptive optics (AO) is a technique used for real-time correction of phase aberrations by employing feedback to adjust the optical system. Polarization aberrations represent another significant type ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.200082 reviews intelligent adaptive optics. Adaptive optics technology can correct the dynamic aberrations of optical system at ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

Das Bundesministerium für Wirtschaft und Energie (BMWi) fördert gemeinsam mit Mitteln aus dem Europäischen Sozialfonds ein Projekt an der Technischen Fakultät der Universität Freiburg im Programm ...

Although active optics can ensure that a telescope's main mirror always retains a perfect shape, the turbulence of the Earth's atmosphere distorts images obtained at even the best sites in the world ...
