  • Maire, A. -L.; Galicher, R.; Boccaletti, A.; Baudoz, P.; Schneider, J.; Cahoy, K.; Stam, D.; Traub, W. (Amsterdam Netherlands: SPIE - The International Society for Optical Engineering, 2012)
    Several small space coronagraphs have been proposed to characterize cold exoplanets in reflected light. Studies have mainly focused on technical feasibility because of the huge star/planet flux ratio to achieve in the ...
  • Cahoy, K.; Fischer, D.; Spronck, J.; Demille, D. (SPIE - The International Society for Optical Engineering, 2010)
    Exoplanets can be detected from a time series of stellar spectra by looking for small, periodic shifts in the absorption features that are consistent with Doppler shifts caused by the presence of an exoplanet, or multiple ...
  • Cahoy, K.; Marinan, A.; Kerr, C.; Cheng, K.; Jamil, S. (SPIE - The International Society for Optical Engineering, 2012)
    The goal of the CubeSat Deformable Mirror Demonstration (DeMi) is to characterize the performance of a small deformable mirror over a year in low-Earth orbit. Small form factor deformable mirrors are a key technology needed ...
  • Defrere, D.; Stark, C.; Cahoy, K.; Beerer, I. (SPIE - The International Society for Optical Engineering, 2012)
    The inner solar system, where the terrestrial planets formed and evolve, is populated by small grains of dust produced by collisions of asteroids and outgassing comets. At visible and infrared wavelengths, this dust cloud ...
  • Douglas, Ewan S.; Hewawasam, Kuravi; Mendillo, Christopher B.; Cahoy, Kerri L; Cook, Timothy A.; Finn, Susanna C. Finn; Howe, Glenn A.; Kuchner, Marc, J.; Lewis, Nikole K.; Marinan, Anne D.; Mawet, Dimitri; Chakrabarti, Supriya (SPIE, 2015-09)
    We describe a set of numerical approaches to modeling the performance of spaceflight high-contrast imaging payloads. Mission design for high-contrast imaging requires numerical wavefront error propagation to ensure accurate ...
  • Belikov, R.; Pluzhnik, E.; Connelley, M. S.; Witteborn, F. C.; Lynch, D. H.; Cahoy, K. L.; Guyon, O.; Greene, T. P.; McKelvey, M. E. (SPIE - The International Society for Optical Engineering, 2009-01-01)
    Direct imaging of extrasolar planets, and Earth-like planets in particular, is an exciting but difficult problem requiring a telescope imaging system with 1010 contrast at separations of 100 mas and less. Furthermore, the ...
  • Clark, James; Cahoy, Kerri (Utah State University Digital Commons, 2016-08-10)
    Free-space optical communication attracts interest due to its promise of higher data rates for similar size, weight, and power costs compared with radio systems. However, while satellite-to-ground optical communication has ...
