1. A light field imaging system for producing an image of an object, the light field imaging system comprising: a primary optical subsystem that forms an optical image of an object, the optical image located at an image plane of the primary optical subsystem; a light field sensor module comprising a secondary imaging array and a sensor array, the secondary imaging array imaging a pupil of the primary optical subsystem onto the sensor array, the secondary imaging array displaced from the image plane so that the sensor array is configured to capture an array of multiplexed views of the object; a processing module configured to determine one or more optical parameters to achieve a desired resolution enhancement value, wherein the primary optical subsystem and/or light field sensor module are adjustable according to the one or more optical parameters; and an auto defocus module to automatically adjust the primary optical subsystem and/or light field sensor module according to the one or more optical parameters determined by the processing module; and wherein the processing module is further configured to combine the captured array of multiplexed views into a digital image of the object having a resolution higher than a resolution of any of the multiplexed views, and wherein the array of multiplexed views were captured after automatic adjustment by the auto defocus module.
