Abstract

Diffraction-limited infrared images of three binary stars reconstructed using speckle imaging techniques are presented. Three methods of recovering the objects' Fourier amplitudes are compared, Fourier deconvolution, projection onto convex sets, and CLEAN. The objects' Fourier phases are retrieved via bispectral analysis. It is shown that the quality of the final reconstructed images is a function of the percentage of the total bispectral volume utilized in the reconstruction procedure.
