Abstract
In this paper, we describe an algorithm which permits recovery of a diffraction limited image from a set of turbulence degraded images. This algorithm, first proposed by Knox and Thompson, can be considered as an extension of the speckle interferometry technique. Turbulence dependence and photon noise limitations are considered and difficulties arising from phase dislocations in the Fourier transform are discussed. The effectiveness of the algorithm has been demonstrated for extended objects. Reconstructions for test patterns degraded in a laboratory turbulence simulation facility are presented. Requirements for a real-time processing system for present and future telescopes are discussed.
