Archived from the original PDF on 10 August Michelson-Morley experiment conducted with white light.
In the first detection of gravitational waves was accomplished using the LIGO instrument, a Michelson interferometer with 4 km arms. 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  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.
Retrieved 3 April 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.
Fig-Squeezed ifo E RS. Media in category “Michelson interfdrometro The following 94 files are in this category, out of 94 total. Speed of light measurement device, Albert A. For different applications of the interferometer, the two light paths can be with different lengths or incorporate optical elements or even materials under test. Michelson interferometer with corner cubes.
When using a noisy detector, such as at infrared wavelengths, this offers an increase in signal to noise ratio while using only a single detector element; 2 the interferometer does not require a limited aperture as do grating or prism spectrometers, which require the incoming light to pass through a narrow slit in order to achieve high spectral resolution.
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. The emergent beam is recorded by an imaging system for analysis.
The high coherence length of a laser allows unequal path lengths in the test and reference arms and permits economical use of the Twyman-Green configuration in testing large optical components.
On the other hand, intdrferometro white broadband light, the central fringe is sharp, but away from the central fringe the fringes are colored and rapidly become indistinct to the eye. The phase-conjugating Michelson interferometry is a promising technology for coherent summation of laser amplifiers .
Another application of the Michelson Interferometer is in optical coherence tomography OCTa medical imaging technique using low-coherence interferometry to provide tomographic visualization inteerferometro internal tissue microstructures. A practical Fourier transform spectrometer would substitute corner cube reflectors for the flat mirrors of the conventional Michelson interferometer, but for simplicity, the illustration does not show this. HMI observations will help establish the relationships between the internal dynamics and magnetic activity in order to understand solar michelsoj and its effects.

Each of those light beams is reflected back toward the beamsplitter which then combines their amplitudes using the superposition principle. The other interferometer arm is bounced off a reference mirror.
The characteristics of the interference pattern depend on the nature of the light source and the precise orientation of the mirrors and beam splitter. The Michelson interferometer is a common configuration for optical interferometry and was invented by Albert Abraham Michelson.

That can be only micrometers for white light, as discussed below. Retrieved 29 April Both beams recombine at point C’ to produce an interference pattern incident on the detector at point E or on the retina of a person’s eye. The basic characteristics distinguishing it from the Michelson configuration are the use of a monochromatic point light source and a collimator. As shown in Fig.

If Interferojetro is an extended source rather than a point source as illustrated, the fringes of Fig. 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.
