Abstract:

The effectiveness of programmed and adaptive control of the phase of a light beam, propagating in a medium with large-scale nonuniformities whose freezing time is comparable to the convection time, is analyzed by means of a numerical experiment. A model of an elastic mirror, deformed by transverse forces and bending moments, is used as the actuator. The conditions under which adaptive control gives a higher light density in the observation plane than programmed correction are determined.
