| Abstract: |
We present a new “pathway" in the form of an innovative space-based telescope: the Fresnel Imager. It is a concept of two spacecrafts flying in formation, one satellite holding a diffraction array acting as entrance pupil and providing a very high wavefront quality in the visible and UV domains, the other one holding the focal instrumentation and detectors. The distance between spacecrafts would vary between 1 and 100 km, depending on the specifications, and the aperture size would be 3 to 100 meters. We present the validation prototypes realized, the spectral domains that can be explored, and the astrophysical targets. |
