title = "Closed-loop wavefront correction for high-contrast imaging: The {"}peak-a-boo{"} algorithm",
abstract = "High contrast imaging from space must overcome photon noise of the diffracted star light and scattered light from optical components defects. The very high contrast required (up to 10 -10 for terrestrial planets) puts severe requirements on the wavefront control system, as the achievable contrast is limited by the quality of the wavefront. The {"}Peak-a-boo{"} correction algorithm, presented here, is a closed loop correction method for the shaped pupil coronagraph to minimize the energy in a pre-defined region in the image where terrestrial planets would be found. The reconstruction part uses three intensity measurements in the image plane with a pinhole added to the shaped pupil for diversity. This method has been shown in simulations to converge to the nominal contrast in 2-3 iterations. In addition, the {"}peak-a-boo{"} has shown to be effective in broadband conditions.",
