| Глоссарий по неразрушающему контролю в авиации |
- In radiologic testing, a family of radioscopic techniques that use backscatter. backscattering, infrared: reflection of thermal energy, whether generated by the ground and reflecting off clouds or unwanted front surface reflections from transparent objects.
- В радиологических исследованиях - семейство радиоскопических методов, в которых используется обратное рассеяние. обратное рассеяние, инфракрасное излучение: отражение тепловой энергии, генерируемой землей и отражающейся от облаков, или нежелательные отражения от передней поверхности от прозрачных объектов.

Backscatter, английский
- (1) interaction of radiation with matter such that the direction of travel after scattering is over 90 degrees and often close to 180 degrees to the original direction of travel. (2) in transmission radiologic testing, interaction of radiation with matter behind the image plane such that scattered radiation returns to the image plane, often adding fog and noise that interfere with production of an image of the specimen. (3) of scatter imaging, interaction of incident radiation with a specimen that scatters the radiation through large angles frequently greater than 90 degrees to the original direction of travel. such radiation is used to form an image or to measure a parameter of the specimen, usually through digital techniques.
- (1) взаимодействие излучения с веществом, при котором направление движения после рассеяния составляет более 90 градусов и часто близко к 180 градусам к первоначальному направлению движения. (2) при трансмиссионном радиологическом тестировании взаимодействие излучения с веществом за плоскостью изображения, при котором рассеянное излучение возвращается в плоскость изображения, часто добавляя туман и шум, которые мешают получению изображения образца. (3) визуализация рассеяния - взаимодействие падающего излучения с образцом, который рассеивает излучение под большими углами, часто превышающими 90 градусов, к первоначальному направлению движения. такое излучение используется для формирования изображения или измерения параметров образца, обычно с помощью цифровых методов.

Backscatter (rt), английский
Secondary radiation that is deflected at angles greater than 90 degrees with respect to the original direction of motion. such radiation should be filtered from the film, as they bring no information to the film and cause a reduction in contrast due to an increase in noise
Backscatter coefficient, английский
The ratio of the optical pulse power (not energy) at the otdr output to the backscatter power at the near end of the fiber (z0). this ratio is inversely proportional to the pulse width, because the optical pulse power is independent. it is expressed in db
Backscattering, английский
- Часть светового потока в оптическом волокне, имеющая обратное направление распространения. возникает за счёт отражений (см. также релеевское рассеяние)
- Scattering of light in the direction opposite to that in which it was originally traveling. the return of a portion of scattered light to the input end of a fiber; the scattering of light in the direction opposite to its original propagation.
- Обратное рассеяние

Image, английский
- Storage, translation and reproduction система хранения, передачи и воспроизведения записанных (на пленку) изображений
- Integrated mapping and geographic encoding system
- The likeness of an object produced by a lens or optical system.
- The optical reproduction of an object, produced by a lens or mirror. a typical positive lens converges rays to form a "real" image which can be photographed. a negative lens spreads rays to form a "virtual" image which can`t be projected.
- A representation of the functional pattern on a substrate
- Any representation of form or features, but esp. one of the entire figure of a person; a statue, effigy, bust, relief, intaglio, etc.
- A sensation, e.g. a smell, sight or taste, which is remembered clearly
- The illusory sound field located between two stereo speakers.
- Visual representation of a test object or scene.
- Visual representation of an object or scene.
- Reproduction of an object produced by light rays. an image forming optical system gathers a beam of light diverging from an object point and transforms it into a beam that converges toward another point, thus producing an image.

Image amplifier, английский
Image amplifier (rt), английский
A device that enhances a radiographic image for the purpose of decreasing interpretation time or increasing image detail.
Image amplitude, английский
Image analysis, английский
- Анализ изображений
- The tools and techniques used to break an image into its component parts so that the program can understand or classify an image.

Image analyzer, английский
A sophisticated microscopic system involving a microscope, a television camera, a dedicated computer, and a viewing monitor similar to a television screen.

Reflection, английский
- The abrupt change in direction of a light beam at an interface between two dissimilar media that returns the beam into the medium where it originated, i.e., a mirror
- A light ray incident on an air to glass interface will have some of its energy redirected back toward its origin due to reflection at the interface.
- The return of radiant energy (incident light) by a surface, with no change in wavelength.
- The bouncing off of light which falls upon a surface.
- The change of direction which a ray of light, sound, or radiant heat undergoes when it strikes a surface; also
- 1. the image of somebody or something which is seen in a mirror or still water 2. the process of reflecting something, especially light, sound or heat 3. careful thought 4. a situation in which an anatomical structure bends back upon itself
- The process of obtaining information about assemblies and the types defined within them, and creating, invoking, and accessing type instances at run time.
- When light bounces back from a surface
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection.2,6
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection (iesna 1984). see also diffuse reflection; specular reflection.
- The act of thinking deeply about one`s actions, behaviour`s, and progress, often facilitated by a coach or mentor to promote self-awareness and learning.
Reflecting, английский
Reflections, английский
Out-of-control reflections can hurt your image; controlled ones can enrich it. tips: keep the subject in full sun, the reflecting surface, such as water, in shade. reflections on water are most pronounced when the lens is at a low angle. most mirrors add a greenish cast to the image. normal mirrors add a "ghost reflection" to the main reflection; use a first surface mirror for critical images.
Transparent, английский
- An object or material that transmits both light and undiffused images. tip: try lighting a plain back-ground directly behind the object, not the object.
- Capable of transmitting light so that objects or images can be seen as if there were no intervening material.
- Общедоступная информация в вто присутствует принцип открытого обмена информацией, осуществляемый с целью осведомить всех членов о принимаемых решениях и вопросах, обсуждаемых на совещаниях и встречах маленьких групп

Artificial source, английский
- Point where elastic waves are created to simulate an acoustic emission event. the term also denotes a device used to create the waves.
- Точка, в которой создаются упругие волны для имитации акустической эмиссии. этот термин также обозначает устройство, используемое для создания волн.
