Virgo is a Michelson interferometer that is isolated from external disturbances : its mirrors and instrumentation are suspended and its laser beam operates in a vacuum.

Its discovery was reported in 1948 by Martin Ryle and Francis Graham-Smith, astronomers at Cambridge, based on observations with the Long Michelson Interferometer.
33.
In 1892 " 93 the Michelson interferometer was used to determine the length of the metre in terms of the wavelength of the red line of cadmium.
34.
In particular, John Davis and Hanbury Brown became convinced that a Michelson interferometer would be cheaper to build and have superior performance to a new intensity interferometer.
35.
The Twyman Green interferometer, a double path interferometer, is a variant of the Michelson interferometer that is commonly used to test the precision of optical surfaces and lenses.
36.
When used as a tunable narrow band filter, Michelson interferometers exhibit a number of advantages and disadvantages when compared with competing technologies such as Fabry P�rot interferometers or Lyot filters.
37.
In 1901, Robert Francis Earhart, while investigating the conduction of gases between closely spaced electrodes using the Michelson interferometer to measure the spacing, discovered an unexpected conduction regime.
38.
Its three satellites form a giant Michelson interferometer in which two " slave " satellites play the role of reflectors and one " master " satellite the one of source and observer.
39.
She implemented a Michelson interferometer using really cheap components and techniques . she demonstrated that her piezoelectric positioner could reproducibly move a mirror to any position across six wavelengths of red light.
40.
In the example of a Michelson Interferometer, a single fringe represents one wavelength of the source light and is measured from the center of one bright line to the center of the next.
