Scientific paper

The novel family of optical/IR telescopes discussed combine the principles of radio astronomy's interferometric image synthesis with computational phase retrieval. The present consideration of such 'optical synthesis telescope' design principles and technology readiness criteria, as well as possible modes of operation and applications, proceeds on the assumption that it should not be necessary to maintain tighter mechanical tolerances than those conventionally required for radio telescopes. Design goals are accordingly reached through reliance on heterodyne detection followed by purely digital processing; useful S/N values are obtained by multiplexing parallel channels with the aid of LSI techniques. These telescopes can also be used for the imaging of space vehicles.
