Paper Abstract

The spatial modulated wavefront conjugated laser signals structure destruction out of the isoplanatic zone theoretically and experimentally examined and the results of experimental investigations are cited. The method of laser signals structure disturbances diminishing is suggested. It based both on reemitted laser signal wavefront conjugation and amplitude spatial modulation of this signal in the plane of optical systems aperture. The spatial filters for arbitrary nontemporal structure of laser signals in object plane are offered. It was proved that some atmospheric lies exist along which there are no influence of atmospheric turbulence on spatial structure of laser signals. The efficiency of the suggested method was examined experimentally by Earth-lied atmospheric line of 500th meters length and IAG wavefront conjugated pulse laser. The possibility of amplitude and phase spatial structure of laser signals maintain and its parameters guidance out of the isoplanatic zone is confirmed.
