Abstract
A technique for storing high-spatial-frequency information in low-freq uency, zero signal regions of an image spectrum has been implemented a nd evaluated. This technique can be used for sparse arrays of small te lescopes acting to synthesize a larger pupil, and reduces the number o f detectors required in the 2-D image focal plane by a factor of 4.
