|1.||physics any acoustic, optical, or microwave instrument that uses interference patterns or fringes to make accurate measurements of wavelength, wave velocity, distance, etc|
|2.||astronomy a radio or optical array consisting of two or more telescopes separated by a known distance and connected so that the radiation from a source in space undergoes interference, enabling the source to be imaged or the position of the source to be accurately determined|
|a white, crystalline, water-insoluble, powerful high explosive, C3H6N6O6, used chiefly in bombs and shells.|

|interferometer (ĭn'tər-fə-rŏm'ĭ-tər) Pronunciation Key
Any of several optical, acoustic, or radio frequency instruments that use interference phenomena between a reference wave and an experimental wave or between two parts of an experimental wave to determine wavelengths and wave velocities, measure very small distances and thicknesses, and calculate indices of refraction.
