Abstract

The use of a symmetric two-grating interferometer as an effective achromatic device for imaging through a phase distorting medium was explored previously.¹ The theory was developed for image restoration through solving a set of nonlinear simultaneous equations obtained by the discrete samplings of intensity and phase at designated sites within the interference field. We have reduced the theory to practice for a specific astronomical problem: the imaging of a double star through turbulence.
