Paper Abstract

A possible system for imaging an exo-planet uses a telescope, coronagraphic mask, and Lyot stop. However, the optics must be nearly flawless for a planet to be imaged, since imperfections cause the image to have speckles which mask the planet. The speckle pattern can be suppressed by removing its phase with an adaptive optic and by reimaging it through a lens with a small, central obscuration. We show how phase diversity can be used to determine the phase.
