Abstract
It are evaluated characteristics of an simulation stand on adaptive optics. The stand is created on the basis of LCAO IOA SB RAS in order to work out algorithms for adaptive correction, research and testing of measuring equipment. The stand allows generating turbulence with given parameters for a particular flexible mirror. In this case, a wave front with different turbulent inhomogeneities with varying their intensity is formed, and the wind transfer of inhomogeneities in the plane of the entrance aperture of the system is also set. For the deflector [1] included in the stand scheme, the tilt angles of the optical radiation are programmed. The Shack-Hartman wavefront sensor and, in parallel with it, a split photodetector measure the characteristics of the incoming optical radiation, which are compared with given parameters. The flexible mirror and deflector reproduce turbulence with given parameters and slopes, respectively.
