Example of the use of adaptive optics observing the surface of the Sun, at the Vacuum Tower Telescope in Tenerife, Spain.
The system works by redirecting part of the light and computing the aberrations suffered by the wavefront. These computations are entered at the entrance mirror. This mirror has a deformable surface, so the computer calculate the instant anti-aberration than compensates the influence of the atmosphere. Making these many tines per second creates a unblurred still image far better than the uncorrected one.

This is the future, Wow.
