optical transmission
11Optical communication — is any form of telecommunication that uses light as the transmission medium. An optical communication system consists of a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a… …
12Optical 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… …
13Optical 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… …
14Optical sectioning — is the process by which a suitably designed microscope can produce clear images of a focal planes deep within a thick sample. This is used to reduce the need for thin sectioning using instruments such as the microtome. Many different techniques… …
15Optical interferometry — combines two or more light waves in an optical instrument in such a way that interference occurs between them. Early interferometers used white light sources and also monochromatic light from atomic sources (e.g., Young s double slit experiment… …
16Optical circulator — symbol An optical circulator is a special fiber optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber, analogous to the operation of an electronic circulator. An optical circulator is… …
17Optical Cable Corporation — Optical Cable Corporation, Inc. Type Public (NASDAQ: OCC) Industry Fiber optics Founded Roanoke, Vir …
18Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… …
19Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… …
20Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
