Abstract:
The efficiency of an experimental adaptive-optics system is studied as applied to stabilization a solar disk fragment image on the entrance slit of a spectrograph. The studies were performed at the Big Solar Vacuum Telescope of the Institute of Solar-Terrestrial Physics SB RAS. Depending on the atmospheric conditions, the variance of image jitter on the spectrograph slit was reduced by a factor from 16 to 40 when applying the adaptive-optics system. The relative error of regulation did not exceed 25%. The harmonics of the image displacement signal at the frequencies of 0 to 30 Hz were effectively suppressed.
