Technical requirements for high contrast imaging

Abstract

We summarize the scientific potential of high contrast optical space imaging for studies of extrasolar planets, debris disks, and planet formation. The unique scientific capabilities offered by a 2-m class optical telescope, the technical requirements to achieve 10^-9 contrast, and the programmatic means needed to advance such a mission are discussed.
