“…When creating, adjusting, and testing adaptive optics systems used in astronomy and vision systems in a turbulent atmosphere [1][2][3][4][5][6], the problem of atmospheric turbulence emulation becomes relevant, for example, to stabilize the radiation image on the photoreceiving matrix of an optical system [7,8].…”

“…A pinhole diaphragm (3) and zooming optics (4) form a collimated beam, the diameter of which is set by an adjustable diaphragm (5). The beam passes over the electric heating element (6), which creates thermal air flows and causes turbulent distortions in the beam, and enters the combining beam-splitting cube (7).…”

“…The signal from the video control camera enters the computer (12) and is used to set up and control the operation of the stand elements, to measure the turbulent characteristics of the beams. Also, the computer through the electric heating elements control unit (13) ensures the formation of thermal air flows over the electric heating elements (6,11,21,27) and their intensity to create the required turbulence in the optical beams. The computer through the control units (14,15,16) programmatically sets the tilts of the deflector mirrors (9,8,17), forming the tilt angles of the wave front of the corresponding beams.…”

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.
