Narrow-Angle Astrometry with the VLT Interferometer

We discuss the merits of a narrow-angle (up to 40 arcsec) astrometric mode for the VLT Interferometer Sub-Array (VISA), which could perform with a precision of the order of 10 micro-arcsec. We present a concept for an astrometric instrument at the combined focus of VLTI.
