Abstract
In adaptive optics systems, to obtain a high-precision result, wave front reconstruction is used according to measurements of the Shack-Hartmann wavefront sensor based on zonal ideology. The zonal approach to reconstruction of the wave front has a good ability to reconstruct local details from the phase surface profile. This is important when correcting turbulent distortions of optical radiation using a segmented mirror, MEMS, and a spatial phase modulator. This paper presents in detail the features of the zonal approach to reconstruction of the wavefront based on measurements obtained by the Shack – Hartmann wavefront sensor.
