Definition of interferometer

Any instrument designed for producing and studying interference of two or more trains of waves or beams of electromagnetic radiation of the same range of wavelengths. Usually denotes an optical interferometer that separates a beam of light into two or more parts that travel in different paths and are then combined together to produce interference fringes.The high resolution thus obtained can be used to separate the components of binary stars or to measure the diameters of stars, planets and their satellites.
