摘要: One of two approaches to implementing NASA's Terrestrial Planet Finder is build a space telescope that utilizes the techniques coronagraphy and apodization suppress diffraction image exo-planets. We present method for calculation telescope's apodizer which suppresses side lobes star so as optimally detect an Earth-like planet. Given shape aperture given search region detector, we solve integral equation determine amplitude modulation (an apodizer) star's energy in focal plane region. The quite general yields special cases product reported by Nisenson Papaliolios (2001) Prolate spheroidal Kasdin et al (2002), Aime (2002). show computer simulations apodizers corresponding point spread functions various aperture-detector configurations.
