Abstract
I will present a proposal for a modification to optical intensity interferometers that allows for sub-microarcsecond astrometry at angular separations as large as several arcseconds. The modification introduces an additional, adjustable path length into the optics, which creates a primary interference fringe for widely separated sources. Combined with recent technological advances in spectroscopy and ultrafast single-photon detection, this design could allow for unprecedented precision in angular resolution of stars. Promising applications include characterization of binary-orbits and stellar properties, exoplanet detection, and Galactic acceleration measurements.
