Light bucket
| Glossary Of Laser Terminology |
An optical receiving telescope that collects photons but is not diffraction limited. its effective field-of-view is larger than a diffraction limited telescope and cannot discriminate particularly well from background noise photons. this may not be a problem if the expected pulsed laser beacon signal is very strong.

Bucket, английский
- An attachment for a materials-handling or excavating machine that digs or carries loose materials such as earth, gravel, stone, or concrete; may be shaped like a scoop, with provision for opening and closing for convenience in unloading.
- Ведро
- A small globe of hoops, covered with canvas, used as a recall for the boats of whalers.
- To lose a bucket over the side was considered a major calamity, far beyond its obvious utility on shipboard since, for some unrecorded reason, anyone who deliberately or accidentally pushed or kicked one overboard was believed to be inviting death on board. this superstitious seafarer’s fear of disaster probably underlies the phrase “kick the bucket.”
- A synonym for bailer; also for calyx.
- Various types and sizes of tubular containers equipped with auger- or other-type cutting edges and used to make borings in earthy or soft formation by rotary methods.
- An open-top can, equipped with a bail, used to hoist broken rock or water and to lower supplies and equipment to men working in a mine shaft or other underground opening.
- A large handhold.
- A virtual container that holds a particular category of items or data.
- Балка, на которой подвешивают окорока, туши и т.п.
- Цена деления (стат.)
Bucket -, английский
- Ковшовый бур buda ~ шнековый бур clay ~ шнековый бур для глин
- Нория, ковшовый элеватор
Bucket auger, английский
A short helical auger incorporating a steel tube to help hold the cuttings on the auger during withdrawal from the drill hole. see auger 1.
Bucket bridge, английский
Пожарная цепочка
Bucket brigade, английский
Цепочка людей, передающих ведра с водой на пожаре
Bucket brigade algorithm, английский
An algorithm used in classifier systems for adjusting rule strengths. the algorithm iteratively applies penalties and rewards to rules based on their contributions to attaining system goals.

Diffraction, английский
- The "spreading" of waves into the lee of obstacles such as breakwaters by the transfer of wave energy along wave crests. diffracted waves are lower in height than incident waves.
- Дифракция
- Deviation of the direction of propagation of a radiation, determined by the wave nature of radiation, and occurring when the radiation passes the edge of an obstacle.
- A wave property which creates deviation from a straight line when the beam passes near an edge of an opaque object. deviation of part of a beam, determined by the wave nature of radiation and occurring when the radiation passes the edge of an opaque obstacle.
- Light curves or travels around small circular objects.
- The changing of direction (bending or spreading) that occurs when a light wave interacts with an opening or barrier
- (1) in acoustics, the reflection of a wave front when passing the edge of an ultrasonically opaque object. (2) in radiation technologies, a special case of scatter, where coherently scattered photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also xray diffraction.
- (1) в акустике - отражение волнового фронта при прохождении края непрозрачного для ультразвука объекта. (2) в радиационных технологиях - особый случай рассеяния, когда когерентно рассеянные фотоны подвергаются интерференции или усилению, что приводит к образованию структур, указывающих на рассеивающую среду. см. также дифракция рентгеновских лучей.
- (1) in radiographic testing, special case of scatter, where coherently scattered (full intensity is retained) photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also x-ray diffraction. (2) in ultrasonic testing, deflection of a wavefront when passing the edge of an ultrasonically opaque object.15
- Deflection of a wavefront when passing the edge of an ultrasonically opaque object.7,22
Discriminate, английский
Отличать; выделять; различать
Particularly, английский
Background, английский
- Фон
- The surface area against which the pattern is contrasted. the surface area of
- The portion of a scene that sits behind the main, foreground subject. the background can be made sharp or unsharp through the use of selective focusing techniques and depth of field manipulation.
- A фоновый; внеязыко- вой knowledge
- Sound or noise that interferes with radio or sonar reception.
- Фон, задний план о ~ for
- A page that you can assign to another page to create multiple layers in a drawing.
- In a graphical user interface such as windows, a pattern or picture in the screen background that can be chosen by the user.
- The area on a card that allows a user to make the card’s image a background when clicked on.
- The area that appears behind the tiles on the start screen.
- The color or image that appears behind the content of a visual element, for example, behind the text that is displayed in a textbox control or on your graphical user interface.
- The image that appears in the conversation window.
- The picture that appears in the photos hub.
- Formations on or signals from a test object that constitute the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. background signals may arise from visual, acoustic, chemical, electrical, or radiation sources that the sensor responds to. see also sensitivity; signal-to-noise ratio.
- Formations on or signals from a test object that constitutes the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. background signals may arise from visual, acoustic, chemical, electrical or radiation sources that the sensor responds to. see also neural acuity; sensitivity; signal-to-noise ratio.
- Formations on, or signals from, a test object that constitute the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. see also background fluorescence; neural acuity; sensitivity; signal-to-noise ratio. glossary b 491
- In magnetic particle testing, the appearance or brightness of the surrounding area acting to reduce the contrast of an indication. (2) nonrelevant signal that tends to interfere with the normal reception or interpretation of the target being sought.
Particular, английский
A частный; конкретный grammar partitioned a разделённый на части sequence 1 одна из базовых операций компьютерной обработки текстов; в каче- стве данных берутся текст либо сегмент текста, грамматика и цель разбора, а на выходе получается удовлетворяющее цели множество значений категориальной отнесённости сегментов в виде, например, дерева разбора. 2 применяется запоминание также и гипотез, выдвигаемых при разбо- ре, и результатов их проверки – м. кэй. 3 используется, в частности, для разбора арифметических выражений. partitioning n членение sentence ~ членение предложений (напр., при переводе )

Beam divergence, английский
- Angle of beam spread measured in radians or milliradians (1 milliradian = 3.4 minutes-of-arc or approximately 1 mil). for small angles where the cord is approximately equal to the arc, the beam divergence can be closely approximated by the ratio of the cord length (beam diameter) divided by the distance (range) from the laser aperture.
- A measure for how fast a laser beam expands far from its focus
Beam splitter, английский
An optical device used to divide the light from a laser into two separate beams -the reference beam and the object beam. it consists of a partially transparent mirror that reflects part of the laser beam and transmits the rest.
