Interferometry - Wikipedia
WEBThe 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 characteristics of the interference pattern depend on the nature of the light source and the precise orientation of the mirrors and beam splitter.

WEBInterference patterns in water. The "interference" occurs in the regions where the waves from the different sources intersect. Similarly, LIGO's interferometer generates an interference pattern by bringing together the laser light waves from the two arms. (Credit: Wikimedia commons)

WEBSep 12, 2022 · As mentioned in Units and Measurement, the length of the standard meter was once defined as the mirror displacement in a Michelson interferometer corresponding to 1,650,763.73 wavelengths of the particular fringe of krypton-86 in a gas discharge tube.
Interferometry explained - Renishaw
WEBLaser interferometry is a well-established method for measuring distances with great accuracy. In order to generate an interference pattern with high precision (distinct fringes), it is very important to have a single highly stable wavelength source, which is achieved using the XL-80 laser.
Interferometry: Measuring with Light - Photonics
WEBA displacement-measuring interferometer (DMI) measures linear motion over ranges from fractions of nanometers to meters while meeting the most stringent accuracy and precision requirements. DMI systems can also be used to measure angular displacement or changes in the refractive index of air.
Basics of Interferometry
WEBThe differential quantities can be used to measure the size and velocity structure of rotating circumstellar disks, outflows, and winds around stars. Differential visibilities (left) and differential phases (right) measured for a star surrounded by a circumstellar disk ( Meilland et al. 2012, A&A, 538, 110 ).
Michelson interferometer | Definition, Description, & Facts
WEBMichelson interferometer, optical instrument that splits a beam of light in two, sends the parts along perpendicular paths, and then brings them back together. It was invented in 1881 by the American physicist A.A. Michelson.
