Abstract
Optical systems are corrected for a variety of aberrations by a microlens array where an optical property of the individual microlenses varies as a function of position in the array. For example, the microlenses can be configured so that the focal length varies to correct field curvature. Representative environments for the microlens array may be characterized by a pixellated source (array of individual sources) in an object plane or a pixellated detector (array of individual detectors) in an image plane, or both.
