SYNTHETIC-APERTURE IMAGING THROUGH AN ABERRATING MEDIUM - EXPERIMENTAL DEMONSTRATION

A simple technique for high-resolution imaging of distant objects is d escribed and experimentally demonstrated. The technique, referred to a s Fourier telescopy, is a variant of Fourier microscopy, which additio nally uses phase closure for correction of intervening aberrations. It is an active-illumination technique that is scalable to angular resol utions of 1 nrad and to illuminators of extremely low power. A laborat ory experiment demonstrates reconstruction of images of two simple obj ects with an angular resolution of 83 mu rad.
