Paper Abstract

A finer-than-sampling-lattice resolution image can be obtained using multiresponse image gathering and Wiener-matrix restoration. The multiresponse image gathering weighs the within-passband and aliased signal components differently, allowing the Wiener-matrix restoration filter to unscramble these signal components and restore spatial frequencies beyond the sampling passband of the photodetector array. Thus, A multiresponse images can be reassembled into a single minimum mean square error image with a resolution that is (root)A times finer than the photodetector-array sampling lattice.
