The technique is based on probing of the spatial coherency of synchrotron radiation in the visible spectral region. The light source PETRA III at DESY (Hamburg, Germany) is using this type of interferometer since several years in order to resolve vertical emittances of about 10 pm.rad. In order to overcome some inherent disadvantages in this setup, a new optical diagnostics beamline was recently commissioned with a two-dimensional interferometer, thus allowing to measure beam sizes in both transverse planes simultaneously. This contribution summarizes the status of the interferometer with first operational experience and describes systematical studies concerning the stability and possibilities to increase the sensitivity on small beam sizes using an intensity imbalance technique.
