摘要：
We will present the concept of Ground Layer Adaptive Optics the Ritchie-Chretien telescope Zeiss- 2000 (F/8), operated at the Institute of Astronomy of the Russian Academy of Sciences. To correct the tip-tilt of the wavefront, we will use NGS. To do this, it is planned to place a separate tracking camera in the wide field of view of the telescope. To correct the slopes, we will use a deflector equipped with an electronic damping system, which allows us to stabilize the responses of the mirror surface. Rayleigh LGS will be used to correct atmospheric aberrations of higher orders. In order to expand the field of anisoplanatism, we plan to perform spatial modulation of the LGS signal in accordance with scientific goals. Synchronization of the spatial modulator and the Sha.k-Hartmann wavefront sensor with an electro-optical shutter will allow this to be done. The article presents options for the layout of the system, taking into account the preservation of the optical axis of the telescope for attachments.
