The Magdalena Ridge Observatory Interferometer (MROI) will be a reconfigurable (7.5-345 meter baselines) 10 element optical/near-infrared imaging interferometer atop Magdalena Ridge, 30 miles west of Socorro, NM. Depending on the location of each unit telescope, light can travel distances ranging from 460 to 660 meters via several reflections that redirect the beam's path through the beam relay trains, delay lines, beam reducing telescope, switchyards and finally to the beam combiners. All of these sub-systems comprise the three major optical axes of the MROI defined by the unit telescope (UT), the delay lines and the beam reducer (DL/BR), and the beam combiners (BC). The purpose of the alignment system is to provide a method of coaligning these three axes. One major obstacle in designing the automated alignment system (AAS) is the required simultaneous measurements from the visible through near-IR wavelengths. Another difficulty is making it fully automated, which has not been accomplished at other optical/near-IR interferometers. The conceptual design of the AAS has been completed and is currently in its preliminary design phase with some prototyping already commenced. Here is presented the current outline and progress of MROI's automated alignment system design and some results of the prototyping.
