Infrared Spatial Interferometer : ウィキペディア英語版 | Infrared Spatial Interferometer The Infrared Spatial Interferometer (ISI) is an astronomical interferometer array of three 65 inch (1.65 m) telescopes operating in the mid-infrared. The telescopes are fully mobile and their current site on Mount Wilson allows for placements as far as 70 m apart, giving the resolution of a telescope of that diameter. The signals are converted to radio frequencies through heterodyne circuits and then combined electronically using techniques copied from radio astronomy. ISI is run by the UC Berkeley Space Sciences Laboratory. The longest (70m) baseline provides a resolution of 0.003 arcsec at a wavelength of 11 micrometers. On July 9, 2003, ISI recorded the first closure phase aperture synthesis measurements in the mid infrared. ==External links==
