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.

Adaptive optics work is on-going at Marshall Space Flight Center. The primary emphasis of our work was on reducing the complexity of the adaptive optics control system, and included the following specific tasks.
The first task was to assess the current technology relating to the laser power beaming system, which in full scale is called the Beam Transmission Optical System.

More importantly, this reveals that small scale wavefront errors contribute only modestly to the overall limitations of the NRM technique without very high-order AO systems, and that future e orts need focus on temporal stability and wavefront.

Finally. Observations of the solar surface from the ground are severely affected by turbulence of the Earth's atmosphere. Beside selecting observatory sites for excellent atmospheric quality, the careful design of the observing equipment, and the application of modern methods that undo the effects of the atmosphere or recover degraded data provide a wealth of information on small-scale : O.

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.
