optical steering
1Optical 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… …
2Optical axis grating — Optical 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 …
3Optical 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… …
4Optical 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… …
5Optical switch — This article is about the optical component. For the optoelectronic component, see Slotted optical switch. In telecommunication, an optical switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be… …
6Beam steering — (also spelled beamsteering or beam steering) is about changing the direction of the main lobe of a radiation pattern. In radio systems, beam steering may be accomplished by switching antenna elements or by changing the relative phases of the RF… …
7Reconfigurable optical add-drop multiplexer — A reconfigurable optical add drop multiplexer (ROADM) is a form of optical add drop multiplexer that adds the ability to remotely switch traffic from a WDM system at the wavelength layer. This allows individual wavelengths carrying data channels… …
8Comparison of high definition optical disc formats — This article is about comparative HD optical disc formats. For a history of the Blu ray/HD DVD format war, see High definition optical disc format war. This article compares the technical specifications of multiple high definition formats,… …
9High definition optical disc format war — The high definition optical disc format war was a format war between the Blu ray Disc and HD DVD optical disc standards for storing high definition video and audio. These standards emerged between 2000 and 2002 and attracted both the mutual and… …
