Abstract:

The results of atmospheric studies of a possibility of compensating for the beam deviation from a direction specified by means of shifting the energy center of gravity of the optical image of the beam scattering volume are presented. The experiments were carried out with collimated and focused beams. The image of the laser spot on the scattering atmospheric layer was recorded by an array detector located in the sharp-image plane of a telescope. The laser beam propagation direction was controlled with a rotary mirror. It is shown that the beam deviation can be compensated for accurate to several microradians.

Keywords:

laser beam, wavefront, atmospheric backscatter, misalignment of optical axes, compensation, image center of gravity
