An application of far-field optimization to dynamic compensation of atmospheric turbulence is reported. The new method eliminates the need for a wave-front sensor, which is required in conventional adaptive-optical systems, and utilizes simple measures of the point-spread function as figures of merit. Far-field optimization employs the simplex algorithm to configure a segmented or continuous (rubber) deformable mirror iteratively to a state that is conjugate to the local atmospheric turbulence. The authors achieve significant adaptive-optics correction with far-field optimization in the presence of both static and dynamic Kolmogorov turbulence.
