 interference fringe
 干擾條紋

 Fringe n.
 1. An ornamental appendage to the border of a piece of stuff, originally consisting of the ends of the warp, projecting beyond the woven fabric; but more commonly made separate and sewed on, consisting sometimes of projecting ends, twisted or plaited together, and sometimes of loose threads of wool, silk, or linen, or narrow strips of leather, or the like.
 2. Something resembling in any respect a fringe; a line of objects along a border or edge; a border; an edging; a margin; a confine.
    The confines of grace and the fringes of repentance.   --Jer. Taylor.
 3. Opt. One of a number of light or dark bands, produced by the interference of light; a diffraction band; --  called also interference fringe.
 4. Bot. The peristome or fringelike appendage of the capsules of most mosses. See Peristome.

 In·ter·fer·ence n.
 1. The act or state of interfering; as, the stoppage of a machine by the interference of some of its parts; a meddlesome interference in the business of others.
 2. Physics The mutual influence, under certain conditions, as from streams of light, or pulsations of sound, or, generally, two waves or vibrations of any kind, producing certain characteristic phenomena, as colored fringes, dark bands, or darkness, in the case of light, silence or increased intensity in sounds; neutralization or superposition of waves generally.
 Note: ☞ The term is most commonly applied to light, and the undulatory theory of light affords the proper explanation of the phenomena which are considered to be produced by the superposition of waves, and are thus substantially identical in their origin with the phenomena of heat, sound, waves of water, and the like.
 3. Patent Law The act or state of interfering, or of claiming a right to the same invention.
 Interference figures Optics, the figures observed when certain sections of crystallized bodies are viewed in converging polarized light; thus, a section of a uniaxial crystal, cut normal to the vertical axis, shows a series of concentric colored rings with a single black cross; -- so called because produced by the interference of luminous waves.
