Laser beam pointing based on the backscattered aerosol beam. A model experiment

Abstract

We present the experimental results of studying the possibility of compensating the misalignment of the axes of a laser beam, focused in an aerosol volume, and a receiving telescope from the shift of an image formed by a laser beam backscattered by aerosol particles of 0.5–0.6 μm. It is shown that the compensation can be carried out accurate to a few microradians via control of the position of the intensity distribution centroid of the image of the beam formed by the scattering volume.
