Paper Abstract

This paper presents the experimental laboratory interferometer simulator implemented to prepare the VSI-Vitruv instrument. In its final phase, VSI-Vitruv will recombine up to 6 beams of the VLTI thanks to a set of planar Integrated Optics (IO) combiners. This simulator will be used to characterize the IO combiner concepts developed for VSI-Vitruv and will allow to optimize the system up to the data reduction and image reconstruction issues. The simulator consists of three sub-systems: a binary object simulator, a VLTI simulator presenting an array of 8 telescopes, the IO beam combiner and a low resolution spectro-imager. After a detailled presentation of the bench, we will present the first validation tests and the performances of the experiment. The characterizations of the combiners developped for VSI-Vitruv are presented in the accompanying paper (Benisty et al.,6268-89).
