TAILIEUCHUNG - Fiber Optics Illustrated Dictionary - Part 7

The Fiber Optics Illustrated Dictionary - Part 7 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary Angstrom angstrom symb. - AAU A A unit of measurement of length named after Anders J. Angstrom. Angstrom applied this unit to the measurement of wavelengths when mapping the Sun s spectrum. It is now also used to express atomic and molecular dimensions. It can be expressed as one ten-billionth of a meter or one tenth of a nanometer or 1 x 1 O 8 centimeters. Angstrom Anders J. 1814-1874 A Swedish scientist who researched the solar system and radiant waves. See angstrom. angular misalignment loss In systems utilizing optical beams a misalignment of fibers mirrors or connecting pieces resulting in the loss of beams that deviate from the desired path. ANI See Automatic Number Identification. ANIK The first domestic communications satellite launched in 1972 by Telesat Canada ANIK was fully operational by 1973. Circuits on the satellite were leased to Radio Corporation of America RCA until RCA had its own satellite. ANIK is actually a series of satellites ANIKs C D and E were built in Canada s David Florida Laboratory DFL facility. The Canadian Broadcasting Corporation was the first television broadcast station in the world to use satellite broadcasting of their shows utilizing ANIK in 1972. See Alouette-1 Canada Space Agency. animate To bring to life to give movement to to move to action to manipulate so as to simulate the effect of movement. animation cell One of multiple elements intended to create the illusion of movement through rapid sequential presentation of a series of cells. These are individual still frames that are similar to one another except in small details drawn on cellophane or another transparent material so that background images and other frames can be sub- or superimposed. Each cell is photographed once or twice depending upon the speed of the movement and the number of images needed. The human visual perception system functions in such a way that such a series of still frames presented at about 24 to 40 frames .
