The Infrared Optical Telescope Array (IOTA) began with an agreement in 1988 among five Institutions, the Smithsonian Astrophysical Observatory, Harvard University, the University of Massachusetts, the University of Wyoming, and MIT/Lincoln Laboratory, to build a two-telescope stellar interferometer for the purpose of making fundamental astrophysical observations, and also as a prototype instrument on which we could perfect techniques which could later lead to the development of a larger, more powerful array. On site construction went on for all 1993 and 1994, with first fringes in December 1993. Jump to: navigation, search 1988 is a leap year starting on a Friday of the Gregorian calendar. ...

In 2000 the third telescope came online providing closure phase observations, allowing aperture synthesis to be performed for the first time at IOTA. The closure phase is an observable quantity in imaging interferometry, which allowed the use of interferometry with very long baselines. ... Aperture synthesis is a type of interferometry that mixes signals from a collection instruments to produce measurements having the same angular resolution as an instrument the size of the entire collection. ...
