[77.09] Analysis of High Contrast Imaging Techniques for Space Based Direct Planetary Imaging

R. G. Lyon, D. Y. Gezari (NASA Goddard Space Flight Center), P. Nisenson (Harvard-Smithsonian CfA)

The recent numerous detections of Jupiter and Saturn like planets in has driven a resurgence in research of space based high contrast imaging techniques for direct planetary imaging. Work is currently ongoing for concepts for NASA's Terrestrial Planet Finder mission and a number of study teams have been funded. The authors are members of one team.

We report on our ongoing investigations of a number of techniques for direct detection and imaging of Earth-like planets around nearby stellar sources. Herein, we give a quantitative analysis of these techniques and compare and contrast them via computer simulations. The techniques we will be reporting on are Bracewell Interferometry, Nisenson Apodized Square Aperture, and Coronagraphic masking techniques.

We parameterize our results with respect to wavelength, aperture size, effects of mirror speckle, both mid- and high-spatial frequency, detector and photon noise as well pointing error.
