Large FOV correction for optical communication with small telescopes using stack of adaptive lenses
Adaptive Optics is playing a fundamental role in correcting for turbulence induced aberrations. Usually, an AO setup is composed of a Deformable Mirror a Wavefront Sensor and can correct only a small patch of the FoV. To tackle this limitation multiple DM’s and WFS’s are used in order to provide a wider corrected patch at the expense of system complexity. We instead propose to use a stack of multi actuator adaptive lenses in order to be able to correct aberrations in a wider FoV respect to the Single Conjugated counterpart.
