Abstract

The Optical Very Large Array (OVLA) and its precursor Micromegas, will be composed of 27 telescopes. Snap-shot images will be formed directly at the combined focus. This will require a densified exit pupil and phased beams for all the wavelengths used. I describe 3 novel algorithms which can, in principle phase such interferometer; they all involve a hierarchy of aperture triplets but use different phasing criteria. I compare here their performance through numerical simulations and in presence of photon noise.
