The Michelson interferometer among other interferometer configurations is employed in many scientific experiments and became well known for its use by Albert Michelson and Edward Morley in the famous Michelson-Morley experiment [1] in a configuration which would have detected the earth’s motion through the supposed luminiferous aether that most physicists at the time believed was the medium in which light waves propagated.

The emergent beam is recorded by an imaging system for analysis.

That can be only micrometers for white light, as discussed below. Another application is a motley of delay line interferometer that converts phase modulation into amplitude modulation in DWDM networks.

Michelson interferometry is one leading method michrlson the direct detection of gravitational waves.

This led to the first polarizing wide-field Michelson interferometer described by Title and Ramsey [22] which was used for solar observations; and led to the development of a refined instrument applied to measurements of oscillations in the sun’s atmosphere, employing a network of observatories around the Earth known as the Global Oscillations Network Group GONG.

Retrieved from ” https: White-light fringes were employed to facilitate observation of shifts in position of the interference pattern. The Michelson Interferometer has played an important role in studies of the upper atmosphererevealing temperatures and winds, employing both space-borne, and ground-based instruments, by measuring the Doppler widths and shifts in the spectra of airglow and aurora. More recently, the Helioseismic and Magnetic Imager HMIon the Solar Dynamics Observatoryemploys two Michelson Interferometers with a polarizer and other tunable elements, to study solar variability and to characterize the Sun’s interior along with the various components of magnetic activity.

In the first detection of gravitational waves was accomplished using the LIGO instrument, a Michelson interferometer with 4 km arms. Both mirrors in a Michelson interferometer can be replaced with Gires—Tournois etalons. The unusual features of phase fluctuations in optical phase-conjugating mirror had been studied via Michelson interferometer with two independent PC-mirrors [33].

At every point on the interference pattern, the power that is not directed to the detector at E is rather present in a beam not shown returning in the direction of the source.

The instrument was an all-glass field-widened achromatically morleey thermally compensated phase-stepping Michelson interferometer, along with a bare CCD detector that imaged the airglow limb through the interferometer.

Archived from the original PDF on 10 August Each of those light beams is reflected back toward the beamsplitter which then combines their amplitudes using the superposition principle. The use of a figured reference mirror in one arm allows the Twyman-Green interferometer to be used for testing various forms of optical component, such as lenses or telescope mirrors.


Even a narrowband or “quasi-monochromatic” spectral source requires careful attention morle issues of chromatic dispersion when used to illuminate an interferometer. The fringes can be interpreted as the result of interference between light coming from the two virtual images S’ 1 and S’ 2 of the original source S.

Narrowband spectral light kichelson a discharge or even white light can also be used, however to obtain significant interference contrast it is required that the differential pathlength is reduced below the coherence length of the light source.
