Scientific paper

A speckle-masking technique for phase recovery is investigated, and the recovered phases are compared with those obtained by the Knox-Thompson phase-difference method as applied to one-dimensional infrared speckle data. Speckle masking involves the computation of a triple correlation (or its Fourier transform, the bispectrum). Results of the application of both phase-recovery algorithms to a bright point source, the nearby binary star Ross 614AB, and its point-source calibrator are presented.
