Investigation of the efficiency of the application of laser guide stars

Abstract

Possibilities of the correction of the general wavefront tilt using a signal from a laser guide star (LGS) are analyzed. The quality of an image of an extraterrestrial object formed by an astronomic optical system through a turbulent atmosphere is analyzed. The efficiency of the adaptive correction of distortions for different LGS schemes is analyzed. Calculations are performed for different models of the vertical dependence of the structural parameter of the refractive index of the turbulent atmosphere.
