A contraction of binary digit; the fundamental unit of digital computing, a bit is either 1 or 0, expressing the binary state of on or off, true or false, etc.

An imaging technique that labels all gray pixels as either black or white before processing begins.

In a CD-ROM disc, the reflective area between nonreflective pits representing a binary-language "off'' as opposed to the "on'' signals of the land-to-pit and pit-to-land transitions.

Diffractive lenses are any optical device that utilizes diffraction in an image-forming capability. Familiar diffractive lenses are zone plates, holographic lenses, kinoform lenses and binary optics.

Binary optics are optical elements, often created by micromachining, lithography or vacuum deposition, that rely on diffraction of the collected energy as opposed to the more common refracting or...
