Focal Plane and Non-linear Curvature Wavefront Sensing for High Contrast Coronagraphic Adaptive Optics Imaging

Olivier Guyon (Subaru Telescope)

Keywords: Adaptive Optics

Abstract:

Wavefronts can be accurately estimated directly from either focal plane images or defocused pupil plane images, in schemes similar to phase diversity. These wavefront sensing techniques offers fundamental advantages over more traditional techniques for high contrast Adaptive Optics. When combined with a high performance coronagraph, these techniques enable efficient detection of exoplanets.
