Abstract

In speckle imaging of astronomical objects, the atmospheric point spread function is commonly estimated by imaging a point source (unresolved single star) near the object of interest either before or after the time of observation. In circumstances where no reliable PSF is available to deconvolve from the data, ‘blind deconvolution’ may be of use. Both direct and indirect or ‘implicit’ blind deconvolution schemes have been applied to (photon-limited) data of binary stars and the implications of these results for referenceless speckle imaging are addressed.
