Astrometric Imaging Telescope optical system

The Astrometric Imaging Telescope will detect extra-solar planetary systems with imaging and astrometry. The optical system contains a high-efficiency coronagraph and scatter-compensated mirrors to detect Jupiter-size planets around nearby stars. The optical system also is distortion free, tolerant to misalignments, and tolerant to optical surface contamination. This allows for the astrometric precision to detect Uranus-mass planets. A focal plane guider and fine guidance sensor are other elements of the optical design.
