Adaptive Stabilization and Imaging System on the Baikal Large Solar Vacuum Telescope

摘要

The results of experimental studies of the effect of atmospheric turbulence in the adaptive optical image correctionsystem at the Baikal Large Solar Vacuum Telescope (LSVT) are presented. To eliminate the jitter and stabilize the imageon the receiver, the appropriate hardware and software system that corrects the tilts of incoming wave front withfrequencies up to 1 kHz has been developed in the Laboratory of the Coherent Adaptive Optics (LCAO). To obtaindigital images of high resolution, the tip-tilt adaptive system is combined with a post-detection computer processing offrames using fast 2D parallel real time algorithms. Experimental data confirm the high efficiency of the dual adaptivesystem for stabilizing and forming images on the LSVT.
