from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun 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.

from The Century Dictionary.

  • noun An instrument for the measurement of lengths by means of the phenomena resulting from the interference of two rays of light.
