ACTIVE CORRECTION OF ABERRATIONS IN OPTICAL SYSTEMS

Abstract:

A method and apparatus for correcting aberrations over the entire field of view of an optical system, in which a first part of the apparatus applies different pre-compensating aberrations individually to different portions of the field of view, such that aberrations caused by a second part of the apparatus cancel the aberrations applied by the first part. The first part of the apparatus is temporally, angularly, or spatially multiplexed and the second part of the apparatus is spatially or angularly multiplexed such that ray bundles corresponding to subsets of contiguous pixels in an image source are each subjected to corresponding pre-compensating aberrations and subsequent aberrations, resulting in a substantially non-aberrated performance over the entire field of view of the optical system.
