The ability to achieve high-resolution optical imaging is essential in a variety of applications including astronomy and microscopy. Light can be perturbed when propagating through optical systems or ...

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 use of deformable mirrors to correct unwanted optical aberrations in real time is helping applications ranging from astronomy to biophotonics and data storage, reports Neil Savage. Adaptive optics ...
