Abstract
Embodiments of a multi-plenoptic system with image stacking and method for wide field-of-regard (FOR) high-resolution image are generally described herein. The multi-plenoptic system may include a subfield separator to decompose an image within a wide field of view into a plurality of multi-pixel subfields. The subfield separator may rotate a chief ray within each multi-pixel subfield by a differing amount relative to a rotation of other rays of the subfield. The multi-plenoptic system may also include a subfield modulator to selectively block or pass light from at least a portion of one or more of the subfields and a subfield image formation element to relay the portions of the subfields that are passed by the subfield modulator onto substantially overlapping areas of a common image plane. A single focal-plane array (FPA) may be aligned with the common image plane to provide for high-resolution imaging over a wide FOR.
