We describe recent progress with interferometric imaging using the Multiple Mirror Telescope (MMT). All six telescopes can now be phased over a wide field of view simultaneously resulting in a (u, v) plane coverage corresponding to that of a 686 cm aperture telescope. We describe the open-loop phasing control of the MMT for gravitational changes and we describe a concept of an internal cophasing/coalignment system for MMT type telescopes.
