High-contrast imaging with an arbitrary aperture: active correction of aperture discontinuities

High-contrast imaging with an arbitrary aperture: active correction of aperture discontinuities

We present a new method to achieve high-contrast images using segmented and/or on-axis telescopes. Our approach relies on using two sequential Deformable Mirrors to compensate for the large amplitude excursions in the telescope aperture due to secondary support structures and/or segment gaps. In this configuration the parameter landscape of Deformable …
