Abstract:

Results of a laboratory experiment with a laser beam propagated in an artificially created turbulence are analyzed. Methods are described which transform a sequence of video frames with recorded intensity distribution into characteristics of laser radiation. As a result of the expansion of time-dependent functions into a trigonometric Fourier series, the frequency of parameter variations was determined and requirements for the operating speed of an adaptive system designed to compensate for distortions were formulated.

Keywords:

adaptive optics, atmospheric turbulence, laboratory experiment, experimental data processing
