The interferometric visibility (also known as "interference visibility" or "fringe visibility" or just "visibility") quantifies the contrast of interference in any system which has wave-like properties, such as optics, quantum mechanics, water waves, or electrical signals. Generally, two or more waves are combined and as the phase between them is changed (e.g. in an interferometer) the power or intensity (probability or population in quantum mechanics) of the resulting wave oscillates (forming an interference pattern). The ratio of the size or amplitude of these oscillations to the sum of the powers of the individual waves is defined as the visibility.
