Scientific paper

We have developed a novel maximum likelihood method dubbed IRIS (image reconstruction with increased sampling) for reconstructing images that have been blurred by a known point-spread function and recorded on a CCD detector. The IRIS method allows the reconstructed images to be represented on a finer grid than that defined by the CCD detector. We illustrate the method on images of the solar corona obtained with the soft X-ray telescope aboard the Yohkoh satellite. The IRIS method can be adapted easily for use with other imaging systems to provide super-resolved reconstructed images.
