The Infrared Spatial Interferometer (ISI) is a high-resolution aperture synthesis imaging system for the 10-micron region. As in many radio interferometers, heterodyne signal detection and lobe rotation for fringe tracking are employed. A Helium-Neon laser metrology system is used for monitoring critical distances within the telescope optics. Although designed for baselines up to 1000 m, initially the interferometer will have baselines ranging from 4 to 34 m, yielding angular resolutions as fine as 0.030 arcsec. First fringes were detected in June 1988. Since then the system has been successfully operated on 4 m and 13 m baselines.
