A simple technique for high-resolution imaging of distant objects is described and experimentally demonstrated. The technique, referred to as Fourier telescopy, is a variant of Fourier microscopy, which additionally uses phase closure for correction of intervening aberrations. It is an active-illumination technique that is scalable to angular resolutions of 1 nrad and to illuminators of extremely low power. A laboratory experiment demonstrates reconstruction of images of two simple objects with an angular resolution of 83 µrad.
