Abstract
The Multiple Mirror Telescope is an array of six 1.8 m diameter folded Cassegrain telescopes used to achieve the collecting area equivalent to that of a telescope with a single 4.5 m primary mirror. For most applications, the six images are co-aligned in such a way that overlapping images appear to result from a single telescope. Another application requires that the wavefronts from all six telescopes be co-phased within 1 micron, concurrent with co-alignment. This paper describes the successful operation of the co-alignment and co-phasing capabilities, the control system and devices used in the applications, and test results to date.
