The upgrade of the BESSY II storage ring to BESSY VSR* demands additional beam diagnostics for machine commissioning and development. Especially bunch resolved measurements are needed. Currently, transverse beam size measurements are done with X-ray pinhole monitor systems, which cannot provide bunch resolved information. Alternative methods to measure the transverse beam size using synchrotron radiation in the visible spectrum are interferometric techniques, which could also be upgraded to bunch resolved systems. For that purpose a double slit interferometer has been constructed. Commissioning of the system has started and experimental results are discussed and compared with the existing pinhole system.
