The NPOI: an Update on the Upgrades

The NPOI is in the process of adding three AO-equipped moveable 1-meter telescopes, and in the initial stages of adding an infrared beam combiner. Two of the 1-m telescope stations planned will form a 432-m baseline. Hardware upgrades including advanced delay line controllers and improved cameras for the VISION beam combiner are under way, and an improved angle tracking system has been designed and is in the process of acquisition. For 2018, we also plan to integrate our Long Delay Lines, giving delay in discrete increments of 25 m. We will describe the state of these upgrades, as well as highlight some recent results.
