Abstract
The efficiency of adaptive correction of turbulent distortions of optical radiation depends on corrector control using information obtained by a wavefront sensor. A wavefront reconstruction algorithm based on analyzing the spatial transformations of the wavefront during passage of the light field through a Shack–Hartmann wavefront sensor and controlling the operation of the system is proposed.
