The image stabilization of laser radiation at the stand of the adaptive optical system

Under the influence of atmospheric turbulence and as a result of natural vibrations of the adaptive optics system, the radiation images in the focal plane fluctuate in time relative to the laser radiation propagation axis, leading to a change in the wave front tilt angles. When accurate positioning of the focal spot is required, the elimination of angular errors becomes an important point in astronomical observations. Image stabilization on the photo detector matrix of the optical system is performed by the tilt corrector, which is one of the key elements of the software and hardware complex for emulating the tilt of the wave front.
