\n The Magdalena Ridge Observatory Interferometer (MROI) will soon incorporate an Automated Alignment System (AAS) to help limit visibility losses due to beam misalignment to ~ 1%. This paper focuses on two key AAS components: (1) a dual-wavelength beacon at each unit telescope and (2) a detector for measuring the shear and tilt of beams of light arriving from the telescopes in the beam combining laboratory. We share initial results of acceptance tests for these components. Finally, we outline a plan for fully validating their performance against a list of derived requirements.\n

In 2018 first-light with the first telescope was achieved, and having placed the order for the second telescope and associated infrastructure, we are poised to realize the milestone of first-fringes in 2020. Funding for the MROI facility is presently via an agreement between the Air Force Research Lab (AFRL) and the New Mexico Institute of Mining and Technology (NMT) to demonstrate operational capabilities and risk reduction experiments for studying geosynchronous objects with three telescopes. In the early 2000's a key science mission was developed in order to design and deploy the complete facility. In the interim, tremendous progress has been made in astrophysical observations, modeling of phenomena, and theoretical studies in many of these arenas. We present the major elements of our key science mission, grouped into three broad categories: A) the environs of Active Galactic Nuclei, B) star and planet formation, and C) fundamental stellar physical phenomena in time-resolved studies, pulsation/rotation, mass-loss and interactions between binary/hierarchical systems. Additionally, science related to: D) solar system objects, and E) human-made geosynchronous objects will be reviewed. Even in the earliest stages of MROI's operations new science will be possible with only two telescopes owing to our greater sensitivity and reconfigurable array. As more telescopes are deployed imaging will rapidly become feasible, at 4 telescopes, and will surpass currently existing facilities when 7 telescopes are operational. We anticipate making MROI available to the astrophysical community once operational status is achieved and encourage early inquiries into capabilities and ideas for new observations with the facility.

\n The Magdalena Ridge Observatory Interferometer (MROI) is an ambitious project to deploy a 10-telescope optical/near-infrared interferometer capable of imaging statistical samples of galactic and extra-galactic objects with sub-milliarcsecond resolution and sensitivities several magnitudes deeper than feasible today. In 2018 first-light with the first telescope was achieved, and having placed the order for the second telescope and associated infrastructure, we are poised to realize the milestone of first-fringes in 2020. Funding for the MROI facility is presently via an agreement between the Air Force Research Lab (AFRL) and the New Mexico Institute of Mining and Technology (NMT) to demonstrate operational capabilities and risk reduction experiments for studying geosynchronous objects with three telescopes. In the early 2000's a key science mission was developed in order to design and deploy the complete facility. In the interim, tremendous progress has been made in astrophysical observations, modeling of phenomena, and theoretical studies in many of these arenas. We present the major elements of our key science mission, grouped into three broad categories: A) the environs of Active Galactic Nuclei, B) star and planet formation, and C) fundamental stellar physical phenomena in time-resolved studies, pulsation/rotation, mass-loss and interactions between binary/hierarchical systems. Additionally, science related to: D) solar system objects, and E) human-made geosynchronous objects will be reviewed. Even in the earliest stages of MROI's operations new science will be possible with only two telescopes owing to our greater sensitivity and reconfigurable array. As more telescopes are deployed imaging will rapidly become feasible, at 4 telescopes, and will surpass currently existing facilities when 7 telescopes are operational. We anticipate making MROI available to the astrophysical community once operational status is achieved and encourage early inquiries into capabilities and ideas for new observations with the facility. We wish to acknowledge our funding through Cooperative Agreement (FA9453-15-2-0086) between AFRL and NMT.\n

This concise guide provides an introduction to the technique for graduate students and researchers who want to make interferometric observations and acts as a reference for technologists building new instruments. Starting from the principles of interference, the author covers the core concepts of interferometry, showing how the effects of the Earth's atmosphere can be overcome using closure phase, and the complete process of making an observation, from planning to image reconstruction. This rigorous approach emphasizes the use of rules-of-thumb for important parameters such as the signal-to-noise ratios, requirements for sampling the Fourier plane and predicting image quality.

\n Optical interferometry is a powerful technique to make images on angular scales hundreds of times smaller than is possible with the largest telescopes. This concise guide provides an introduction to the technique for graduate students and researchers who want to make interferometric observations and acts as a reference for technologists building new instruments. Starting from the principles of interference, the author covers the core concepts of interferometry, showing how the effects of the Earth's atmosphere can be overcome using closure phase, and the complete process of making an observation, from planning to image reconstruction.

For applications in near-infrared stellar interferometry, this implies an enhancement in the fringe-tracking sensitivity of roughly 20% (in the photon-limited regime) over that which is conventionally realized using a swept mirror.\n
