A description of the stand for an adaptive optics system operating in the mode of emulation of the slopes of the laser radiation wavefront on a turbulent path is given. The potential capabilities of the test bench involve setting the parameters of turbulent distortions characteristic of paths of various lengths, as well as using a piezceramic deflector of wavefront slopes as a source of emulated image distortions in the observation plane. The stand of the adaptive optics system makes it possible to stabilize the jitter of the optical radiation image in the plane of the receiving device with the adaptive correction circuit turned on and off under conditions of various system operation modes.
This development is carried out in the interests of creating a remote optical meter operating on the optical signal of a weak extra-atmospheric source - such as a star. It will allow obtaining data on turbulence for inclined paths at different heights above the underlying surface, and will also make it possible to detect the presence of turbulent layers in the atmosphere, including the presence of non-Kolmogorov turbulence in the atmosphere. For this purpose, it is planned to create two single-channel mock-ups of image jitter meters operating on signals from two different optical sources in a scheme with intersecting lines of sight. Atmospheric experiments have been carried out to compare the results of measurements of atmospheric turbulence by various methods.
