Compensation for Laser Beam Wavefront Aberration Distortions Induced by Aero-Optical Effects along Aircraft–Satellite Paths Based on Backscatter Signals

Abstract—

Results of the numerical study of a possibility of compensating for aero-optical aberration distortions of the beam wavefront using the aperture sensing technique based on atmospheric backscatter signals are described. It is shown that the technique makes it possible to partially compensate for aero-optical aberrations. The cross section beam size becomes several times smaller than that of a beam without the wavefront adaptive control, and the intensity distribution becomes more symmetric about the optical axis.
