ABSTRACT:
Dual-wavelength coherent optical adaptive systems which comprises means for adaptively forming a first beam of a first wavelength, on a target and for deriving therefrom information defining characteristics of phase perturbations in the propagation path to the target; and means responsive to said information for compensating for propagation path distortions for a second beam of a second wavelength which is simultaneously transmitted along a substantially identical path to that of said first beam.
