In 2017, at the Large Solar Vacuum Telescope of the Institute of Solar-Terrestrial Physics of SB RAS, an element base was created for developing methods for recording and correcting distortions of optical radiation passed through a layer of turbulent atmosphere; a three-stage image correction system was installed; software was developed, which provides, the statistical analysis of the quality of the formed image in BSWT and combines the work of a wavefront sensor, an image quality analyzer, and an astronomical instrument - a filter-recorder.
