AO Control with turbulence plates!

This is from Tuesday afternoon.

We closed the adaptive optics control loop in simulated atmospheric conditions (created by a spinning phase plate in the telescope beam simulator). The AO system is correcting aberrations using both the woofer and the tweeter deformable mirror in closed loop at a 1500 Hz control update rate.

Here is a video of the diagnostic screens. Notice how the "wind" blows from upper right to lower left on the DM screens (bottom two).
