2Linnik interferometer — A Linnik interferometer is a two beam interferometer used in microscopy and surface contour measurements or topography. The basic configuration is the same as a Michelson interferometer. What distinguishes the Linnik configuration is the use of… …
3Fizeau interferometer — A Fizeau interferometer is similar to a Fabry Perot interferometer in that they both consist of two reflecting surfaces. In a Fizeau interferometer, however, the two surfaces are usually much less than totally reflecting (4 30%), so that… …
4optical interferometer — ▪ instrument instrument for making precise measurements for beams of light of such factors as length, surface irregularities, and index of refraction. It divides a beam of light into a number of beams that travel unequal paths and whose… …
5Atom interferometer — An Atom interferometer is an interferometer based on exploiting the wave character of atoms.OverviewInterferometry inherently depends on the wave nature of the object. As pointed out by de Broglie in his PhD thesis, particles, including atoms,… …

7radio interferometer — Astron. any of several different types of instrumentation designed to observe interference patterns of electromagnetic radiation at radio wavelengths: used in the discovery and measurement of radio sources in the atmosphere. * * * ▪ astronomical… …
8N-slit interferometer — The N slit interferometer is an extension of the double slit interferometer also known as Young s double slit interferometer. One of the first known uses of N slit arrays in optics was illustrated by Newton.[1] In the first part of last century,… …
9Degree Angular Scale Interferometer — The Degree Angular Scale Interferometer (DASI) was a telescope located in Antarctica. It was a 13 element interferometer operating between 26 and 36 GHz in ten bands. The instrument is similar in design to the Cosmic Background Imager and… …
