Abstract

The random refractive-index fluctuations associated withatmospheric turbulence is induced wavefront distortions of optical wave propagating trough atmosphere.The adaptive optical systems are designedto achievementsdiffractive-limited image by compensating phase aberrations in real time. The efficiency ofadaptive optics correction is limited by time delay and with taking into account the spatial characteristics are defined by isoplanatic patch size. In this paper we investigate theoretically the efficiency of adaptive optics system for atmospheric turbulence correction. We study isoplanatic patch for X and Y tilt wavefront aberrations in Zernike terms depends on characteristics of turbulent atmosphere for the estimations of the spatio-temporal characteristics of adaptive optical system applications.
