Abstract:
1. A multi-plenoptic system, comprising: a fore optic; a first set of lenslets configured to receive incoming rays from the fore optic and decompose an image within a field of view into a plurality of multi-pixel subfields by rotation of a chief ray within each multi-pixel subfield by a differing amount relative to a rotation of other rays of the subfield, the first set of lenslets configured to select pixels for each subfield based on angle of the incoming rays of the image; a spatial light modulator disposed in an optical path after the first set of lenslets, the spatial light modulator including a plurality of spatial light modulation elements, each spatial light modulation element configured to selectively modulate light from at least a portion of one of the subfields to provide for selection and a spatial-temporal encoding of the subfields; a second set of lenslets configured to relay the portions of the subfields that are passed by the spatial light modulator onto substantially overlapping areas of a common image plane; and a plurality of achromatic prisms configured to compress an angle space of the chief rays of each of the subfields to provide a more-parallel alignment of the chief rays prior to subfield image formation by the second set of lenslets.
