light-transmission optics
11light-emitting diode — /luyt i mit ing/. See LED. [1965 70] * * * ▪ electronics in electronics, a semiconductor device that emits infrared or visible light when charged with an electric current. Visible LEDs are used in many electronic devices as indicator lamps …
12Light field — The light field is a function that describes the amount of light traveling in every direction through every point in space. Michael Faraday was the first to propose (in an 1846 lecture entitled Thoughts on Ray Vibrations ) that light should be… …
13Transmission 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… …
14Transmission time — In telecommunication networks, the transmission time, also considered as the propagation delay, is the amount of time it takes a bit to go from the start of the link to its destination node. The propagation speed depends on the physical medium of …

16Faster-than-light — (also superluminal or FTL) communications and travel refer to the propagation of information or matter faster than the speed of light. Science fiction style space travel, dubbed true FTL, defies known physics.Under the special theory of… …
17Fiber optics — Fi ber op tics,, n. that branch of optics which studies the transmission of light through thin transparent fibers. Note: Light transmission through optical fibers has become an important means of data and telephone signal transmission, in some… …
18History of optics — Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek and Indian philosophers, and the development of geometrical optics in the Greco Roman… …
19Fourier optics — is the study of classical optics using techniques involving Fourier transforms and can be seen as an extension of the Huygens Fresnel principle. The underlying theorem that light waves can be described as made up of sinusoidal waves, in a manner… …
