101Retroreflector — Infobox Laboratory equipment name = Retroreflector caption = A gold corner cube retroreflector acronym = other names = uses = Distance measurement by optical delay line inventor = manufacturer = model = related = A retroreflector (sometimes… …
102Microphotonics — is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking. Microphotonics employs at least two different materials with a large differential index of refraction to squeeze the light down to …
103Photographic film — This article is mainly concerned with still photography film. For motion picture film, please see film stock. Photographic film is a sheet of plastic (polyester, nitrocellulose or cellulose acetate) coated with an emulsion containing light… …
104Multilateration — is a navigation technique based on the measurement of the difference in distance to two or more stations at known locations that broadcast signals at known times. Unlike measurements of absolute distance or angle, measuring the difference in… …
105liquid crystal display — n. LCD * * * ▪ electronics Introduction electronic display device that operates by applying a varying electric voltage to a layer of liquid crystal, thereby inducing changes in its optical properties. LCDs are commonly used for portable… …
106Subcarrier multiplexing — (SCM) is a method for multiplexing many different fiber optics based communication link into a single uplink fiber. The SCM (also known as SCMA, SubCarrier Multiple Access) is used in passive optical network (PON) access infrastructures as a… …
107Hans-Georg Weber — (* 30. Dezember 1940 in Troppau, Sudetenland) ist ein deutscher Experimentalphysiker mit den Arbeitsgebieten Laserspektroskopie und optische Signalverarbeitung für die Optische Nachrichtentechnik. Leben Weber studierte ab 1961 in Frankfurt/Main… …
108Mandrel wrapping — In multimode fiber optics, mandrel wrapping is a technique used to preferentially attenuate high order mode power of a propagating optical signal. Consequently, if the fibre is propagating substantial energy in affected modes, the modal… …
