Method for enhanced detection of faint targets in systems employing an external occulter |
摘要 |
One embodiment of the present method and apparatus encompasses a method having the steps of: locating a rotateable occulter between a star having at least one planet and a light detector for detecting light from the star and the planet, the rotateable occulter having a central circular obscuration, and a plurality of hypergaussian-shaped petals that are located around the central circular obscuration; substantially blocking on axis light from the star with the central circular obscuration; rotating the occulter such that light from the planet oscillates due to changing azimuthal orientation; synchronizing the light from the planet to orientation of the occulter; and detecting off-axis light from the planet with the light detector.
