Abstract
The ultimate limitation of visible light high-dynamic-range imaging systems such as shaped pupil coronagraphs comes from scattering caused by imperfections in the optical surfaces of the collecting system, and from the non-uniform reflectivity of those surfaces. This paper focuses on the correction of these imperfections using two deformable mirrors in a zero path length difference Michelson interferometer. Simulations show the advantages and limitations of introducing such a device into a wavefront control loop. Laboratory work shows progres towards high resolution amplitude control.
