Abstract

The phase-gradient process for reconstructing stellar speckle images is implemented in a photon-address mode for application to images containing small numbers of photons. Comparisons are made with an address-mode Knox-Thompson process which show that the phase-gradient approach has computational advantages and better SNR performance. Reconstructions from simulated data and real data for the binary source Beta Delphinius are presented.
