Pereira, S.F. Braat, J.J.M. Faculty Applied Sciences Department Optics Research Groep Date 2006-06-22 Abstract We discuss the previously-reported measurements of a three-beam nulling interferometer without achromatic phase-shifters, using delay lines only. The theoretical rejection ratio of a few thousand has not been achieved experimentally. In order to explain the obtained results, some direct spectral and polarization measurements have been performed. We present here the latest results and discuss some asymmetries in the interference patterns.
