PHASE-DIVERSITY CORRECTION OF TURBULENCE-INDUCED SPACE-VARIANT BLUR

Space-variant blur is encountered when objects extend beyond the isopl anatic patch associated with the intervening atmospheric turbulence. T he method of phase diversity, used to estimate jointly the object and the aberrations, is generalized to accommodate turbulence-induced spac e-variant blur. This generalization utilizes a parametric model for th e blur function that is constructed with multiple phase screens. Simul ation results are presented that demonstrate the recovery of near-diff raction-limited imagery from phase-diversity imagery that has been deg raded with rather severe anisoplanatism.
