In this paper we describe how to correct the errors in digital holography in which phase screens in the propagation path between the object and the detector introduce anisoplanatic (space-variant) blurring in the image. We use a nonlinear optimization approach employing a sharpness metric to correct for the space-variant blur. Numerical propagations of fields are done in such a way as to avoid non-physical aliasing, and the sharpness metric is designed to overcome false atmospheric telescope oversharpening effects. We show reconstruction results for the three-screen case.
