Paper Abstract

A rotating interferometer has been proposed for the detection of faint signals and the reconstruction of their sources. The performance analysis of a two-dimensional interferometer shows that an mterferometer configuration incorporating a non-redundant aperture spacing need not additionally include a rotational feature. The rotation of a two-aperture interferometer is recommended to sample the pupil plane at a large number of angular spatial frequencies and a single radial spatial frequency. A two-aperture interferometer, either stationary or rotating, will not detect a star and its faint companion. If the starplanet separation is correctly estimated in advance in order to set the aperture separation, then a very slowly rotating two-aperture interferometer may be used for detection of this system. Key Terms : Interferometnc arrays, Pupil-plane interferometry, Faint-signal detection, Signal reconstruction.
