Abstract
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.
