Abstract
In this paper we discuss problems in an interferometer which arise when the interferometer uses a conventional, so-called dasianon-cooperativepsila target rather than a mirror. We discuss how the interference signal is influenced by using non-cooperative target which also can depolarize the incident beam. Finally we show how the detrimental effects arising from the speckle field can be reduced when a suitable imaging optics is used.
