Method for atmospheric turbulence profile measurement from observation of laser guide stars

Аннотация

Earlier, the method for retrieval of the atmospheric turbulence profile in two intersecting laser beams that produce laser guide stars has been suggested by the authors. Results of further development of this method are given in this work. For a Kolmogorov turbulence, the integral equation with a sharp kernel like a delta function is built, which allows a simpler and more exact way for retrieving the high-altitude profile as compared to the initial version. Data of a numerical experiment show a good retrieval of the profile of actual turbulence up to altitudes of 10 km.
