Effect of telescope antenna diagram on the data acquisition in a stellar interferometer
Author(s): Emmanuel Longueteau; Laurent Delage; François Reynaud

Paper Abstract

This paper deals with the effect of the telescope size on accuracy of the data acquisition in a optical fibre linked stellar interferometer. In this context we introduce the concept of antenna diagram commonly used for microwaves antennae. This concept is essential to explain the contrasts and the phaseclosure acquisitions corruption in a stellar interferometer. The telescope pointing errors induces additional effects that are superimposed with the field limitation and could become critical.
