As previously mentioned in Introduction to Astronomical Adaptive Optics, the Adaptive optic approach is a powerful tool for minimising the distortions caused by Atmospheric turbulence.
The Shack-Hartmann based Wavefront sensor approach can be seen at The Center for High Angular Resolution Astronomy (CHARA) Array, [2, 3] at the Mount Wilson Observatory. See Figure 1 & 2. The Chara Array is a IR and Near Infrared telescope system comprising of 6 optically connected telescopes, each fitted with an EMCCD (Andor iXon Ultra) based AO system which operates at 1000 frames per second (set up using a 90 x 90 pixel ROI).

And alternative AO implementations can be found at The Large Binocular Telescope which utilises a Laser based guide Star, adaptive secondary mirror with 672 actuators and Andor Zyla sCMOS camera operating at 1 kHz (200 x 200 Pixels). [5,6]
The Raven AO system utilises 5 EMCCD cameras and used multiple objects in a field of view to perform Multi-object correction over a very large image plane.[8,9]
Table 1 Shows a broad range of Adaptive Optic systems and the telescopes where they are based.
