Interferometric beam combination with discrete optics.
We explore the capabilities of discrete diffraction in phase retrieval problems and propose an innovative scheme exploiting a two-dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation function between any pair of three telescopes of an astrointerferometer.
