61Optical interconnect — is a way of communication by optical cables.[1] Compared to traditional cables, optical wires are capable of a much higher bandwidth, from 10 Gb/s up to 100 Gb/s.[2] The technology is currently being introduced as a way to link computers to… …
62Optical character recognition — Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine encoded text. It is widely used to convert books and documents into… …
63Optical 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… …
64Optical axis gratings — (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are different from the… …
65Optical dating — is a method of determining how long ago minerals were last exposed to daylight. It is useful to geologists and archaeologists who want to know when such an event occurred. Alternate names sometimes used are optically stimulated luminescence… …
66Optical format — is a measure of the maximum diagonal size of an imaged object in the focal plane of an optical system. The diagonal size of the imaging sensor (film, CCD or CMOS chip etc.) and the optical format of the lens system must be matched. The optical… …
67Optical brightener — Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents (FWAs) are dyes that absorb light in the ultraviolet and violet region (usually 340 370 nm) of the electromagnetic… …
68Optical Carrier — levels describe a range of digital signals that can be carried on SONET fiber optic network.cite web | title = Synchronous Optical Network (SONET) | work = Web ProForums | publisher = International Engineering Consortium | url =… …
69Optical disc authoring software — is computer software for authoring optical discs including CD ROMs and DVDs. They are also known by synonyms such as CD burning application or DVD authoring software. Such software is required to use an optical disc recorder.Creating an optical… …
70Optical molasses — Schematic Optical molasses is a laser cooling technique that can cool down neutral atoms to temperatures colder than a magneto optical trap (MOT). An optical molasses consists of 3 pairs of counter propagating circularly polarized laser beams… …
