Abstract

Deconvolution is a necessary tool for the exploitation of adaptive opticscorrected images, because the correction is partial. The Maximum APosteriori (MAP) framework is used to derive a deconvolution method(MISTRAL) thatcombines the data with our knowledge of the noise statistics as well as ourprior information about the object and the variability of the Point SpreadFunction. The deconvolution of experimental and scientific data illustrates the capabilitiesof this method.
