Abstract

We consider the problem of reconstructing remotely obtained images from image-plane detector arrays. While the individual detectors may be larger than the blur spot of the imaging optics, high-resolution reconstructions can be obtained by scanning or rotating the image with respect to the detector. As an alternative to matrix inversion or least-squares estimation the method of convex projections is proposed. We derive the appropriate algorithm and discuss the availability of prior knowledge. The application of the algorithm to tomography is briefly reviewed.
