- A system containing two or more signals that are combined in phase to cause interference.
- An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. interferometers are used extensively for testing optical elements during manufacture. typical designs include the michelson, twyman-green and fizeau interferometers.
