Optical Long Baseline Interferometry - Principles and Instrumentation

Denis Mourard , Nicolas Nardetto (1)

1 LAGRANGE - Joseph Louis LAGRANGE

The principles of optical long baseline interferometry are presented firstly from the point of view of the coherence of the stellar wavefront and secondly from the point of view of the Object-Image relationship. These two complementary approaches permit to extract some important considerations for the actual implementation of this imaging technique. We also present a panorama of the currently operational optical interferometers and their most recent science programs. We conclude by a short prospective on the future steps.
