Two-Mirror Apodization for High-Contrast Imaging (2007)
Wesley A. Traub, Robert J. Vanderbei
Direct detection of extrasolar planets will require imaging systems capable of unprecedented contrast. Apodized pupils provide an attractive way to achieve such contrast but they are di#cult, perhaps...
Speckle noise reduction techniques for high-dynamic range imaging (2007)
Bordé, Pascal J., Traub, Wesley A.
High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to...
Coronagraph Workshop papers (2007)

Speckle nulling for exoplanet detection with space-based coronagraphic telescopes (2006)
Borde, Pascal J., Traub, Wesley A., Kern, Brian D., Trauger, John T., Kuhnert, Andreas C.
To detect Earth-like planets in the visible with a coronagraphic telescope, two major noise sources have to be overcome: the photon noise of the diffracted star light, and the speckle noise due to...
Comparative Planetology and the Search for Life Beyond the Solar System (2006)
