interference pattern (plural interference patterns)
(physics) A series of light and dark bands that map out the way in which the phase difference between two waves varies in space.

Examples
Because the frequency of light waves (~10 14 Hz) is too high to be detected by currently available detectors, it is possible to observe only the intensity of an optical interference pattern.
Between two plane waves Geometrical arrangement for two plane wave interference Interference fringes in overlapping plane waves A simple form of interference pattern is obtained if two plane waves of the same frequency intersect at an angle.
Dispersion: two sinusoids propagating at different speeds make a moving interference pattern.
If the light from two point sources overlaps, the interference pattern maps out the way in which the phase difference between the two waves varies in space.
Remarkably, however, an interference pattern emerges when these particles are allowed to build up one by one (see the image to the right).
RLG A ring laser gyroscope relies on the Sagnac effect to measure rotation by measuring the shifting interference pattern of a split beam of light as it moves around the ring in opposite directions.
