<title>Alignment And Phasing Of Deployable Telescopes</title>

Abstract

We describe the experiences in coaligning and phasing the MMT, together with studies in setting up radio telescopes. We discuss these experiences and on the basis of them, we suggest schemes for coaligning and phasing four large future telescopes with complex pri-mary mirror systems. These telescopes are MT2, a 15m equivalent MMT, The University of California Ten Meter Telescope, the 10m sub-mm wave telescope of the University of Arizona and the Max Planck Institute for Radioastronomy, and the Large Deployable Reflector, a future space telescope for far IR and sub-mm waves.
