Paper Abstract

Many techniques have been suggested for diffraction-limited imaging of stellar objects from Earth-based telescopes. In this paper we review the methods that use the short-exposure images collected by Labeyrie's technique of stellar speckle interferometry [1,2]. These methods may be divided into two groups: those that use only the modulus of the Fourier transform of the object intensity (i.e. the quantity normally determined by speckle interferometry) and those that use the original short-exposure images. The latter methods, which include the shift-and add, Knox-Thompson, McGlamery and exponential filter techniques, show more promise in the case of astronomical imaging.
