Adaptive optics is a class of components that can be added to optical systems to improve their performance. They do this by reducing the incoming wave distortions which can arise due to natural ...

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 ...

"Twinkle, twinkle, little star" is a twisted sort of lullaby for astronomers, because the effect that enchants the casual stargazer blurs images taken by even the most powerful telescopes. Sometimes ...

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 ...

Stars in the night sky appear to twinkle because air moving in the atmosphere disrupts starlight before it reaches our eyes. While this phenomenon might make for a great nursery rhyme, it causes major ...

Optical system design and optimisation is a dynamic field that integrates principles of geometrical optics, advanced mathematical modelling and modern computational techniques to enhance the ...

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 ...

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 ...

The next generation of adaptive optics has arrived at the Large Binocular Telescope (LBT) in Arizona, providing astronomers with a new level of image sharpness never before seen. Developed in a ...

The European Southern Observatory’s (ESO) Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of ...

In 1610, Galileo used a telescope to discover the four largest moons of Jupiter, and for more than two hundred years the only way to get a better look at the night sky was to build a bigger telescope.
