Reconstruction of astronomical images has been performed by phase retrieval methods from autocorrelation or, equivalently, power spectrum data estimated by applying the stellar speckle interferometry (S.S.I.) technique to photon-limited, turbulence degraded, short exposure images. We present results obtained from real data, and also from computer simulated data. We make comparisons of the results depending both on the phase retrieval method used, and on whether we impose the available information in the object space (autocorrelation), or in the spatial frequency space (power spectrum).
