Paper Abstract

Speckle masking1-4 is a triple correlation method that can overcome image degradation caused by the atmosphere, by telescope aberrations and by image motion of the speckle interferograms (guiding errors etc.). True images are obtained since it is possible to reconstruct both the modulus and the phase of the object Fourier transform. In other words, speckle masking is a solution of the phase problem in speckle interferometry.5 Other speckle methods are described in Ref. 6.
