Abstract

A technique for storing high spatial frequency information in low frequency zero regions of an image spectrum has been implemented and evaluated. This technique can be used for sparse arrays of small telescopes acting to synthesize a larger pupil. The number of detectors required in the two-dimensional image focal plane is reduced by a factor of four.
