interferometer: see interference interferometer. When the wavelength of the light is known, the interferometer indicates the thickness of the film by the interference patterns it forms. The reverse process, i.e., the measurement of the length of an unknown light wave, can also be carried out by the interferometer.

(optics)
An instrument in which light from a source is split into two or more beams, which are subsequently reunited after traveling over different paths and display interference.
