Abstract
Systems and methods are disclosed for improving image quality by modifying received radiation wavefronts with one or more uncalibrated variable phase plates at the pupil plane of the optical system, to produce an atmospheric-like blurred image on the focal plane with an effective increase in the sampling parameter Q. Real-time image restoration algorithms may then be applied to data sets sampled from the blurred image formed on the detector array. Numerous phase plate embodiments are provided for modifying the wavefront.
