One of the firstastronomical interferometers was built on the Mount Wilson Observatory'sreflector telescope in 1920 in order to measure the diameters of stars.The red giant star Betelgeuse was among the first to have its diameterdetermined in this way. This method was extended to measurements usingseparated telescopes by Johnson, Betz and Towns (1974) in the infraredand by Labeyrie (1975) in the visible. In the late 1970s improvements incomputer processing allowed for the first 'fringe-tracking'interferometer, which operates fast enough to follow the blurringeffects of astronomical seeing, leading to the Mk I,II and III series ofinterferometers. Similar techniques have now been applied at otherastronomical telescope arrays, including the Keck Interferometer and thePalomar Testbed Interferometer.…

The Rayleighinterferometer employs two beams of light from a single source, anddetermines the difference in optical path length between the two pathsusing interference between the two beams when they are recombinedfollowing traversal of the paths. An example is shown in the figure.Light from a source (top) is collimated by a lens and split into twobeams using slits. The beams are sent through two different paths andpass through compensating plates. They are brought to a focus by asecond lens (bottom) where an interference pattern is observed todetermine the optical path difference in terms of wavelengths of thelight. …
