Abstract
Fast adaptive optical system usually used in atmosphere tasks—for wavefront correction of the laser beam passed through a turbulent atmosphere. As a rule, the frequency of waveform distortions is about 100 Hz (roughly). Consequently, the frequency of discreet system should be about 1500 frames per second. Achieving such performance is possible by FPGA using for full closed-loop cycle: image receiving from wavefront sensor, voltages array for deformable mirror calculation the and provision fast applying these voltages to deformable mirror. Main aspects of FPGA using to minimize the whole cycle of adaptive optical system are considered.
The study was carried out with a grant from the Russian Science Foundation (project No. 19-19-00706).
