Authorization, английский
- Разрешение пользователю доступа к ресурсам сети
- Процесс в результате которого происходит проверка наличия денежных средств на счету владельца карты, при котором получается разрешение от банка-эмитента на осуществление операций с использованием платежной карточки. успешная авторизация значит, что денежн
- Разрешение; выдача разрешения
- Лицензия, официальное разрешение. authorized person: уполномоченное лицо.
- Утверждение, уполномочивание. процесс одобрения персонала или методик для использования в работе лаборатории сотрудниками надлежащей квалификации.
- A workflow with activities that must be completed before the approval or validation request is committed to the database.
- The process of granting a person, computer process, or device access to certain information, services or functionality. authorization is derived from the identity of the person, computer process, or device requesting access, which is verified through authentication.

Fiber optics, английский
- Волоконная оптика
- Also called optical fibers or optical fiber bundles. an assemblage of transparent glass fibers all bundled together parallel to one another. the length of each fiber is much greater than its diameter. this bundle of fibers has the ability to transmit a picture from one of its surfaces to the other around curves and into otherwise inaccessible places with an extremely low loss of definition and light, by a process of total reflection.
- A technology designed to transmit signals in the form of pulses of light. fiber optic
- Communications medium based on a laser transmission that uses a glass or plastic fiber which carries light to transmit video, audio, or data signals. each fiber can carry from 90 to 150 megabits of digital information per second or 1,000 voice glossary/32 channels. transmission can be simplex (one-way) or duplex (two-way) voice, data, and video service.
- A technology designed to transmit signals in the form of pulses of light. fiber optic cable is noted for its properties of electrical isolation and resistance to electrostatic and electromagnetic interference.
- The links used for voice, video, data, medical, sensing, and illumination applications. all use optical fibers to transmit or receive optical signals or power
- A system of flexible quartz or glass fibers that use total internal reflection (tir) to pass light through thousands of glancing (total internal) reflections.
- Optics based on optical fibers
- A flexible bundle of light-transmitting fibers used for medical, scientific, and difficult-access situations.
- Guiding light by refraction, the principle that makes fiber optics possible, was first demonstrated by french scientists in the 1840s, and in 1870 englishman john tyndall discovered that light uses internal reflection to follow a specific path. practical applications of this principle appeared early in the twentieth century, but it was not until the late 1950s that modern optical fibers appeared. unlike copper wire, an optical fiber cable is not electrical in nature, carrying information from one point to another in the form of light. a basic system consists of a transmitting device, to generate the light signal; an optical fiber cable, which carries the light; and a receiver, to accept the transmitted signal. fiber optic networks are more powerful and versatile than traditional copper-wire networks, operating at very high speeds and providing high bandwidth. during the second half of the twentieth century, this technology experienced a phenomenal rate of progress, and the u.s. military moved quickly to install fiber optic networks that provide increased information capability to users of high-tech weaponry, command and control systems, global positioning systems, inventory/transportation management programs, personnel/payroll record-keeping, and medical apparatus. fiber optic systems, using floating radio antennae, provide submerged submarines with twoway communications for the first time in history, while similar technology allows them to deploy a floating optical fiber periscope from well below conventional periscope depth.
- Волоконно-оптический кабель; волоконная оптика
- A technology for the transmission of light beams along optical fibers. a light beam, such as that produced in a laser, can be modulated to carry information. because light has a higher frequency on the electromagnetic spectrum than other types of radiation, such as radio waves, a single fiber-optic channel can carry significantly more information than most other means of information transmission. optical fibers are thin strands of glass or other transparent material, with dozens or hundreds of strands housed in a single cable. optical fibers are essentially immune to electromagnetic interference.
- A technology that transmits infrared and visible light frequencies through strands of glass or plastic fiber.
- A communications technology that permits light to travel through hair?thin glass fibers and that increases the data transmission possible within a cable of small diameter.
- Technology of efficient transmission of light through transparent fibers such as glass, quartz, and plastic by means of total internal reflection. field of view (fov): range or area where things can be seen through an imaging system, lens, or aperture. angular subtense (expressed in angular degrees or radians per side if rectangular or in angular degrees or radians if circular) over which an instrument will integrate all incoming radiant energy. in a radiation thermometer, the field of view is the target spot size; in a scanner or imager, the field of view is the scan angle, picture size, or total field of view. compare depth of field.
- Technology of efficient transmission of light through transparent fibers such as glass, quartz and plastic by means of total internal reflection.
- Technology of light transmission through fibers such as plastic, glass or quartz.1
