Interferometry - Wikipedia In 1881, the American physicist Albert A Michelson, while visiting Hermann von Helmholtz in Berlin, invented the interferometer that is named after him, the Michelson Interferometer, to search for effects of the motion of the Earth on the speed of light
What is an Interferometer? | LIGO Lab | Caltech What is an Interferometer? Interferometers are investigative tools used in many fields of science and engineering Pioneered in the mid- to late-1800s, they are called interferometers because they work by merging sources of light to create an interference pattern, which can be measured and analyzed: hence 'Interfere-meter', or interferometer
How do interferometers work? - Explain that Stuff An interferometer is a really precise scientific instrument designed to measure things with extraordinary accuracy The basic idea of interferometry involves taking a beam of light (or another type of electromagnetic radiation) and splitting it into two equal halves using what's called a beam-splitter (also called a half-transparent mirror or
Interferometry explained - Renishaw How does an interferometer work? 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 interferometer
3. 6: The Michelson Interferometer - Physics LibreTexts The Michelson interferometer (invented by the American physicist Albert A Michelson, 1852–1931) is a precision instrument that produces interference fringes by splitting a light beam into two parts and then recombining them after they have traveled different optical paths
Basics of Interferometry - Georgia State University Instead of taking images of stars, an interferometer records the interference pattern (or interference fringes) created by combining the light from two or more telescopes
Introduction to Interferometers, theory and design types Basically, an interferometer splits a beam of light (usually a laser) into two components: a reference beam and a sensing beam The reference beam will travel unaltered through an optical path
