Direct Optical Imaging is necessary to characterize exoplanets spectroscopically in most cases (non-transiting planets), and to address the habitability of terrestrial planets around sun like stars. The chapter studies the science objectives, observatory architectures, and needed technology developments as a function of mission scale. Possible architectures can be based on internal coronagraphs or external occulters. The Optical Imaging chapter details the association between Astrometry or RV and imaging in space, expanding on the ExoPTF recommendations for flagship and probe-scale missions. Indirect methods (astrometry or radial velocities) are necessary to obtain a direct measurement of the masses, orbital parameters, and planet "addresses". Careful Design Reference Mission (DRM) development over the next several years will articulate the tradeoffs in cost and performance between imaging missions with and without astrometric precursors. In the short term a probe-scale direct imaging mission can be combined with existing and future Radial Velocities and ground-based Astrometry for the characterization of mature giant planets, Neptunes, and super Earths. A probe scale will also detect and characterize exozodiacal disks, a problem ExoPTF identified as critical for future terrestrial planet imaging missions. This strategy is independent from a space astrometric mission both in terms of scientific goals and timing sequence. The chapter also identifies the critical technologies for the various imaging architectures, for which the maturity is linked to flight requirements ranging from probe-scale to flagship. The chapter provides a brief overview of each technology and its state-of the-art.
