Optical power meter — in use An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually… … Wikipedia
Optical mark recognition — (also called Optical Mark Reading and OMR) is the process of capturing human marked data from document forms such as surveys and tests. Contents 1 OMR background 2 OMR software 2.1 Open Source … Wikipedia
Optical coherence tomography — Intervention Optical Coherence Tomography (OCT) image of a sarcoma MeSH … Wikipedia
Optical 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… … Wikipedia
Optical burst switching — (OBS) is an optical networking technique that allows dynamic sub wavelength switching of data. OBS is viewed as a compromise between the yet unfeasible full optical packet switching (OPS) and the mostly static optical circuit switching (OCS). It… … Wikipedia
Optical imaging — is an imaging technique. Optics usually describes the behavior of visible, ultraviolet, and infrared light used in imaging. Because light is an electromagnetic wave, similar phenomena occur in X rays, microwaves, radio waves. Chemical imaging or… … Wikipedia
Optical tomography — Intervention MeSH D041622 Optical tomography is a form of computed tomography that creates a digital volumetric model of an object by reconstructing images made from light transmitted and scattered through an … Wikipedia
Optical fiber, nonconductive, riser — (OFNR) is a type of optical fiber cable. As designated by the National Fire Protection Association (NFPA), this name is used for interior fiber optic cables which contain no electrically conductive components, and which are certified for use in… … Wikipedia
Optical Burst Switching — (OBS) is an experimental switching paradigm representing an intermediate solution between circuit (wavelength) and packet switching in optical networks. PurposeIts purpose is to dynamically provision sub wavelength granularity by optimally… … Wikipedia
Optical lift — is an optical analogue of aerodynamic lift, in which a cambered refractive object with differently shaped top and bottom surfaces experiences a stable transverse lift force when placed in a uniform stream of light.[1] Contents 1 Discovery 2… … Wikipedia
