In the upcoming generation of Extremely Large Telescopes, the impact of the turbulent atmosphere is corrected by Adaptive Optics systems. Even after correction the quality of astronomical images is degraded, e.g., due to time delay coming from measurement/correction processes resulting in a blur in images. We present an approach for the reconstruction of the directional dependent PSF using, e.g., atmospheric tomography. Finally, a blind deconvolution algorithm for the improvement of the scientific image is used.
This presentation is part of Minisymposium “MS34 - Numerical Linear Algebra techniques for Image Restoration and Reconstruction (2 parts)”
