noun

physics the distinctive pattern of light and dark fringes, rings, etc, formed by diffraction

diffraction pattern

The interference pattern that results when a wave or a series of waves undergoes diffraction, as when passed through a diffraction grating or the lattices of a crystal. The pattern provides information about the frequency of the wave and the structure of the material causing the diffraction.
See also interferometer

If the aperture and wave-length increase in the same proportion, the size and shape of the diffraction pattern undergo no change.

The diffraction pattern is therefore that due to a single aperture, merely brightened n times.

By this procedure the width of the central band in the diffraction pattern is halved, and so far an advantage is attained.
