Scientific paper

A technique for storing high-spatial-frequency information in low-frequency, zero signal 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, and reduces the number of detectors required in the 2-D image focal plane by a factor of 4.
