Abstract

Mozurkewich presented a beam combiner design suitable for use with a large number of apertures. Such a system has applications both in space and as a camera for single-aperture, ground-based telescopes. We implemented a version of this design which accommodates ~ 90 apertures and resolves the fringes into more than 100 spectral channels. The resulting system, which has been tested in the laboratory, provides over 50,000 simultaneous, independent fringe measurements. Implementation details and test results are presented.
