Abstract:

Subject of research. New capabilities of the wavefront sensor of the Shack–Hartmann type are analyzed. Purpose of the work. Comparison of experimental results of the operation of Shack–Hartmann wavefront sensors for various atmospheric optics problems: a classic wavefront sensor on horizontal atmospheric paths when working with laser radiation, a correlation wavefront sensor on the Large Solar Vacuum Telescope when forming an image of an extended object through atmospheric turbulence, and modified wavefront sensors for analyzing the state of atmospheric turbulence. Method. Various applications of Shack–Hartmann wavefront sensors are described and measu rement results are presented. Main results. The data on the operation of the Shack–Hartmann wavefront sensor on various atmospheric paths are presented, using several microlens rasters of variable dimensions, which made it possible to work in changing conditions of the level of atmospheric turbulence. Practical significance. The results obtained in the work can be used for developments of adaptive optics systems and for studying the atmospheric turbulence on the propagation path of optical radiation.
