The AGILIS concept allows the implementation of many different array configurations, and the adaptation of the array to the size of the observed object. Top: array configuration. Bottom: instantaneous (u, v) coverage at zenith. Left to right: circular, Y rotating, Y aligned, and linear array configurations, ordered in increasing maximum to minimum baseline ratio (Bmax/Bmin). Two optimized array scales are presented for observations at a wavelength of 2 μm: Bmin =200 m for a 1′′ m object (large blue dots), and Bmin =40 m for a 5′′ m object (small green dots).
