    The volume deals with adaptive optics, meaning optical systems that measure and correct wavefront aberrations in real time. In the jargon of the specialist, COAT (coherent optical adaptive techniques) reshapes rubber mirrors to compensate for such degrading effects as atmospheric turbulence, inhomogeneous laser mediums, and time varying figure.   PROCEEDINGS VOLUME Adaptive Optics Systems V.

Adaptive optics is a way forward that avoids this dilemma. It works like this. Light from an astronomical object travels in straight lines through the vacuum of space so the wavefront, or set of waves that left the object at the same time, defines a flat as the light travels through the atmosphere, its speed depends slightly on density, and the turbulent motions of air in the upper.
