Paper Abstract

In this paper we present the status of different experiments set up at Turin Observatory on novel techniques for multiple beam combination, adopting mostly bulk optics. The goal of these experiments is to find the best scheme able to perform efficient fringe tracking operation on a densely populated (N>4) interferometer, while at the same time maximizing optical throughput and sensitivity on faint sources. One of these concepts has been proposed for the VSI fringe tracker (see Corcione et al, this conference). The schemes proposed have also the advantage of being in principle easily adapted to a large number of beams.
