Abstract
This paper summarizes the limits of ground-based interferometry for differential astrometry as well as ground-based interferometry for direct detection of exo-planets and exo-zodi dust levels. For direct detection, ground-based interferometry at near IR wavelengths using large telescopes with adaptive optics offers a significant advantage over single telescopes with adaptive optics. Ground-based differential astrometry for exo-planet detection is extremely accurate with sufficient accuracy to detect Neptune mass planets around 400 – 600 nearby stars. Ground-based tnterferometry using large (>6m) telescopes is also capable of detecting the 10 μm emission of the zodiacal light around nearby stars with zodi levels similar to our solar system
