Focus
|
- Фокус; фокусировать
- That spot where the wavefront originating at a point on the source is converged to form a point image. fresnel reflection, fresnel lossesthe fraction of the incident radiation specularly reflected by an interface between two media of different refractive indices.
- As a noun, the point where rays of light meet which have been reflected by a mirror or refracted by a lens, giving rise to an image of the source. as a verb, to adjust focal length for the clearest image and smallest spot size.
- Causing light to form a point, or sharp image on the image sensor or film.
- A point through which rays of light converge or from which rays of light appear to diverge when entering or emerging from an optical system.
- 1. the point where light rays converge through a lens 2. the centre of an infection (note: the plural is foci.) verb 1. to adjust a lens until an image is clear and sharp 2. to see clearly he has difficulty in focusing on the object.
- Фокус
- N фокус | a фокусный class
- A point where converging rays or lines meet.
- The search topic selector menu from which you can select an item that an analysis focuses on.
- Position of a viewed object and a lens system relative to one another to offer a distinct image of the object as seen through the lens system. see accommodation and depth of field. focus, principal plane of: single plane actually in focus in a photographic scene.
- Position of a viewed object and a lens system relative to one another to offer a distinct image of the object as seen through the lens system. see accommodation and depth of field. focus, principal plane of: single plane in focus in a photographic scene. focusing, automatic: (1) feature of a camera whereby the lens system adjusts to focus on an object in the field of view. (2) metaphorical attribute of a borescopic instrument’s depth of field (the range of distance in focus). the depth of field is so great in the case of video borescopes that focusing is unnecessary for most applications. despite the name, no mechanism is actively adjusted. the large depth of field is due both to the small diameter of the lens aperture and to the proximity of the lens to the charge coupled device. focusing, primary: focusing by the lens of the image onto a fiber optic bundle at the tip of a probe. focusing, secondary: focusing at the eyepiece of a borescope or other optical instrument, specifically the manual refocusing needed when the viewing distance changes. footcandle (ftc): disfavored unit of illuminance, where 1 ftc = 1 lm·ft–2 = 10.76 lx. footlambert (ftl): disfavored unit of luminance, where 1 ftl = 3.426 cd·m–2.

- Position of a viewed object and a lens system relative to one another to offer a distinct image of the object as seen through the lens system. see accommodation and depth of field.1 focusing, automatic: (1) feature of camera, usually incorporating a range finder, whereby the lens system adjusts to focus on an object in part of the field of view. (2) metaphorical attribute of a borescopic instrument’s depth of field (the range of distance in focus). the depth of field is so great in the case of video borescopes that focusing is unnecessary for most applications.1 longer depths of field are obtained by reducing the optical aperture. focusing, primary: focusing of an image by the lens onto a fiber optic bundle at the tip of a probe.1 focusing, secondary: focusing at the eyepiece of a borescope or other optical instrument, specifically the manual refocusing needed when the viewing distance changes.1 focus, principal plane of: single plane actually in focus in a photographic scene.1 foreground temperature (see instrument ambient background): temperature of the scene behind and surrounding the instrument as viewed from the target.

Фокус, русский
- Фокус, штука, искусство, кунштюк, фокус-покус; средоточие, центр. , суть, уловка, центр
- (лат.) — источник, очаг болезненного процесса.
- (от лат . focus - очаг, огонь) в оптике, точка, в которой собирается прошедший через оптическую систему параллельный пучок световых лучей. если пучок параллелен оптической оси системы, то фокус также лежит на оси и называется главным.
- (от нем . hokuspokus), искусный трюк, основанный на обмане зрения при помощи ловких и быстрых приемов. в переносном смысле - уловка, хитроумный прием.
- В искусственном интеллекте совокупность знаний, активизируемая при формировании или интерпретации сообщения на естественном языке.
- Точка, на оптической оси объектива, в которой сходятся все лучи по выходе из оптической системы, при условии, что на оптическую систему падает параллельный пучок лучей (от бесконечно удаленного источника света).
- Точка на главной оптической оси, в которой пересекаются после преломления лучи (или их продолжения), падающие на линзу параллельно главной оптической оси.

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.
