Abstract
The possibility of applying adaptive-optics devices to ground-based solar astronomy and high-resolution spectroscopy is considered. Schemes of adaptive-optics systems with quadrant and correlation image shift detectors are proposed. Results of their testing in the Big Solar Vacuum Telescope of the Baikal Astrophysical Observatory are presented. It is shown that an adaptive system with the quadrant detector will reduce the dispersion of image fragment jittering in the neighborhood of a crater by a factor of 16
