Nature and Aims of the Single Aperture Imaging group
The Single Aperture Imaging group covers the theme of high contrast imaging on monolithic telescopes. It involves not only coronagraphy (attenuation of the coherent starlight) but also the problematic related to the speckle noise and hence the techniques of wavefront control, super polishing, and differential imaging (by mean of spectroscopy, polarimetry or coherence). The primary goal is to make a status of the various techniques developed in Europe and then to evaluate their maturity (lab/sky experiments, limitations & solutions, development plan, schedule and cost) in order to identify their potential contribution in a roadmap.
