Abstract:

The ways of further development of a multistage adaptive system for stabilization and image formation at the Large Solar Vacuum Telescope are suggested. The system was created at IAO SB RAS with the technical support of ISTP SB RAS, tested, and proved to be effective. In this system, the first stage provides image stabilization, the second stage corrects the wave-front shape using a flexible mirror controlled by a special wave-front sensor, and the third stage is post-detector frame processing. For post-detector correction of digital images, special processing software was developed based on high-speed parallel algorithms. The system can be improved by means of creating high-speed correlation tracking algorithms and adding a second set of wave-front sensor and flexible mirror mounted in a plane conjugate to the altitude of a layer of strong local turbulence.
