Abstract
Anisoplanatic effect caused by atmospheric turbulence is an important issue affecting the imaging resolution of ground-based telescopes when observing astronomical objects. Based on the optimized multilayer phase screens distribution model on inhomogeneous turbulent path, this paper establishes a theoretical model of telescope imaging related to optical system parameters. The effects of aperture, photon limited and optical aberration on anisoplanatic imaging are analyzed. The results show that aperture has obvious influence on diffraction effect of short-exposure point spread functions (PSFs), and the defocusing aberration only slightly affect the anisoplanatic imaging and do not influence on restoration methods of such images.
