Paper Abstract

Coherent arrays of telescopes, either ground or space based, are likely to become in the next decade a new class of powerful and wide-spread astronomical instruments. It has often been argued that at optical wavelengths these arrays are only able to measure the modulus of the source's spatial spectrum, and therefore are poorly suited for imaging. In this paper we show that phase reconstruction techniques developed for speckle interferometry can be applied to two telescopes Michelson interferometry. We make the comparison between image plane and pupil plane interferometry and compute a merit factor: for modulus determination, pupil plane is always preferable, while image plane is better for phase retrieval.
