Paper Abstract

Following the first demonstration of an all guided two-beam stellar interferometer designed for space missions, we report an experiment recombining the beams coming from three telescopes using only guided optics or integrated optics components. This additional aperture could give us the possibility to achieve an image reconstruction using the phase-closure technique. We focus these calibration experiments on the interference fringe contrast measurements and the evolution of the phase-closure term versus the differential dispersion effects induced by the stretching of fiber delay lines.
