METHOD AND DEVICE FOR EVALUATING PARAMETERS CHARACTERIZING ATMOSPHERIC TURBULENCE

摘要

The invention relates to a method for characterizing the atmospheric turbulence, comprising: acquiring images of a celestial object by means of a camera coupled to a small telescope; analyzing the acquired images to determine angle of arrival fluctuations of wavefronts from positions of spots formed by the celestial object in the acquired images; determining variances of the angle of arrival fluctuations; and estimating the Fried parameter from the variances of the angle of arrival fluctuations, by setting an outer scale parameter of the atmospheric turbulence to a fixed median value.
