Abstract

Results of a laboratory experiment with a laser beam propagated in an artificially created turbulence are analyzed. Techniques 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 fluctuations is estimated; requirements for the operating speed of an adaptive system designed for distortion compensation are formulated.
