4optical flat — noun a disk of high quality quartz glass having at least one side ground and polished with a deviation in flatness less than 50 nanometers all over, and a surface quality of 5 microfinish or less; used, in an interferometer, to measure the… …
5Optical disc — Optical media redirects here. For transmission media for light, see Medium (optics). The optical lens of a compact disc drive. In computing and optical disc recording technologies, an optical disc is a flat, usually circular disc which encodes… …
6Optical cross section — or OCS is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is . It is dependent on the geometry and the reflectivity at a particular wavelength of an object. Optical cross… …
7Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… …
8Flat-field correction — is a technique used to improve quality in digital imaging. The goal is to remove artifacts from 2 D images that are caused by variations in the pixel to pixel sensitivity of the detector and/or by distortions in the optical path. It is a standard …
