Abstract

Fourier Telescopy is an imaging method that can form images of very dim objects with angular resolution of a few nanoradians, attained by means of a synthetic aperture that overcomes the effects of intervening aberrations using mathematical algorithms akin to that of long-baseline radio astronomy. The algorithm makes use of phase closure and advanced wavefront reconstruction techniques from adaptive optics and Knox-Thompson image reconstruction. The imaging technique is active and so can be used even with faint objects. The imaging technique is active and encodes the information in the temporal instead of spatial domain, allowing imaging of faint objects with extremely large, low- cost receivers. An implementation for deep space imaging is shown; it uses large-area solar collectors for the receiver, yielding a low-cost, high-performance design. Simulated images are shown for a potential realization of the system.
