Abstract

The Magdalena Ridge Observatory now being planned for a site within the Magdalena Mountains near Socorro, NM will have an optical/near infrared interferometric imaging array as its primary observing instrument. We are presently evaluating the use of array telescope apertures ranging from 1.2 to 2.0 m in diameter for this application. Telescopes in this size range are many times the size of Fried's coherence parameter r₀ anywhere within the .6 to 2.2 μm wavelength range of interest and to be useful for interferometry will require the use of adaptive optics (AO) techniques to restore and maintain the spatial coherence of the telescope pupils. We review some of the practical limitations related to the use of AO systems on interferometer telescopes and discuss the enhanced interferometric performance that might thereby be attained.
