This paper deals with the experimentation and simulation of the telescope directivity effects in the frame of stellar interferometry. Contrasts and phase closure can be corrupted when using large aperture. The corruption becomes very critical if telescope pointing error occurs. We report an example on numerical simulation of contrast and phase closure corruption to be measured for 40 cm and 100 cm telescope diameters. The OAST2 test bench has been used to experimentally demonstrate this data corruption.
