Abstract :
When looking at objects in space, the turbulent effort of the Earth´s atmosphere is an important factor. This paper focuses on the atmospheric effects on incoming light and image restoration methods to restore the formed nonisoplanatic image. Because of its turbulent nature, the atmosphere introduces the Kolmogorov phase onto the incoming light. In this paper, we use two layers of Kolmogorov phase to simulate the atmospheric turbulent effects, then form the nonisoplanatic image. We also analyze the Strehl ratio of the nonisoplanatic image. We show the compared results by use of two different restoration estimators
