Coronagraphic low-order wavefront sensor: Postprocessing sensitivity enhancer for high-performance coronagraphs

Vogt, Frederic; Martinache, Frantz; Guyon, Olivier; Yoshikawa, Takashi; Garrel, Vincent; Matsuo, Taro


Detection and characterization of exoplanets by direct imaging requires a coronagraph designed to deliver high-contrast at small angular separation. To achieve this, an accurate control of low-order aberrations, such as pointing and focus errors, is essential to optimize coronagraphic rejection and avoid the possible confusion between exoplanet light and coronagraphic leaks in the science image. Simulations and laboratory prototyping have shown that a coronagraphic low-order wavefront sensor...[Show more]
