HOW ARE ADAPTIVE OPTICS USED IN SPACE?
Adaptive optics were originally designed to observe distant galaxies and stars.
The technology relies on guide stars to help telescopes to ‘see’ through the blurring caused by Earth’s atmosphere.
The guide star is an artificial light source, in this case a two-photon laser, that corrects atmospheric distortion.
Scientists used a novel imaging technique, which relies on adaptive optics, to see cells in stunning detail. Pictured, they observed cells undergoing mitosis in rapid speeds
Using multiple beams aims to improve image quality over a larger field of view.
With multiple laser beams rather than just one, the turbulence of the atmosphere can be mapped in greater detail.
Researchers from Harvard and other institutions have figured out how to use adaptive optics in lattice light-sheet microscopy using a two-photon laser.
This allows them to view cellular processes in never-before-seen stunning detail.
