1. A resolution-enhanced plenoptic imaging system comprising: a plenoptic imaging system including an overlapping first imaging subsystem and second imaging subsystem; the plenoptic imaging system performing a plenoptic imaging process that is modeled by a pupil image function (PIF); the first imaging subsystem producing a primary image; the second imaging subsystem including: a secondary imaging array positioned approximately at a location of the primary image; and a sensor array positioned to capture a plenoptic image formed by the secondary imaging array; and processing power coupled to the sensor array, the processing power applying a PIF inversion process to the captured plenoptic image to produce an estimate of the object.
