When ground-based telescopes view stars, the light they collect must weave its way through layers of air. When those layers are turbulent, the light gets blurred, so images from observatories with ...

University of California, Berkeley, astronomers have taken advantage of a recently mounted laser guide star system at UC’s Lick Observatory to obtain sharp, twinkle-free images of the faint dusty ...

has received a follow-on, 15-month contract from the Department of Defense's High Energy Laser-Joint Technology Office to continue development of a High Power Adaptive Optic system. The amount of the ...

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 same technology that astronomers are using to sharpen the images from ground-based telescopes is also giving eye specialists better techniques for studying and correcting human vision. SANTA CRUZ, ...

Ground-based telescopes have long contended with atmospheric turbulence that diminishes image clarity, and the advent of adaptive optics combined with laser guide stars has been transformative in ...

ANU and RMIT researchers’ adaptive optics to direct guide star laser being developed by Electro Optic Systems. New guide star laser will enable tracking of space debris at lower altitudes. Researchers ...
