Scientific paper

Lucy's algorithm is iteratively applied in a blind deconvolution method. This new approach permits the reconstruction of a greatly extended object from one speckle frame. Speckle images of extended object may lie partly outside the active region of the detector. Likewise, objects close to the boundary of the detector, but outside of the field of view, may contaminate the image. The blind deconvolution method is adapted to deal with these situations. Repeated use of the blind deconvolution method is also proposed. Computer simulations are conducted and the effectiveness of the proposed method is demonstrated. The method is applied to an image of the solar photosphere.
