Analysis of atmospheric turbulence anisoplanatism

Abstract

The image quality of space object or the Laser propagation characteristics in atmosphere will be degraded by the effect of turbulence. Adaptive optics can be used to correct atmospheric turbulent aberration, but the anisoplanatic effect of atmospheric turbulence is unavoidable. Adopting the special spectral filtering method, different type of anisoplanatism in different scene are systemically modelled, and the formulae that describing different type of anisoplanatic variance and their Zernike model components are obtained. According to HV turbulent outline, the characteristics of Zernike model components of different type of anisoplanatic variance are analyzed.
