Abstract:

There is analyzed the possibility to correcting the general tilt of the wave front on base of the signal from laser guide star (LGS). It is analyzed quality of the image extraterrestrial object, formed by astronomical optical system through turbulent atmosphere. Relative increase the parameter Strehl is calculated under adaptive correction on base of the using the technology of the laser guide stars. It is compared efficiency of adaptive correction the distortions for different type of the guide sources. The calculations are executed for different models of the high-altitude evolution of the structure parameter of the refractive index of turbulent atmosphere.
