|---|---|---|---|
| 설명 | 눈을 한곳에 고정시킨 채, 관찰할 수 있는 주변공간을 시야라 한다. 시야를 검사하는 가장 간단한 방법은 대면검사(confronting test)이다. 이것은 피검사자의 눈을 검사자의 눈에 맞추어 보도록 하여 눈을 고정시킨채, 검사자가 손가락끝을 위쪽, 아래쪽, 왼쪽, 오른쪽, 그리고 비스듬히 경사진 곳 등으로 옮겨보아 피검사자가 관찰할 수 있는지 여부를 정하는 검사법이다. 이보다 정확한 검사법은 자동식 컴퓨터시야검사법이 있다. 대개, 눈자체의 이상이 있어도 시야검사에서 이상이 나오지만, 이외 뇌의 이상으로 시각의 형성경로에 이상이 있어도 역시 이상소견을 보인다. |

| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |

| bright field imaging | <microscopy> An imaging mode in a transmission electron microscopy that uses only unscattered Electrons to form the image. Contrast in such an image is due entirely to mass-thickness variations in amorphous samples, and may include diffraction contrast in crystalline samples. (05 Aug 1998) |
|---|---|
| bright field microscopy | <technique> Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy. (18 Nov 1997) |
| dark field illumination | <microscopy> Any method of illumination which illuminates the specimen but does not admit light directly to the objective. It may be by substage (dark field) condensers, by stagespot lighting, by special condensers fitted around special objectives for reflected illumination or by the slit ultramicroscope. (05 Aug 1998) |
| bright | 1. Radiating or reflecting light; shedding or having much light; shining; luminous; not dark. "The sun was bright o'erhead." (Longfellow) "The earth was dark, but the heavens were bright." (Drake) "The public places were as bright as at noonday." (Macaulay) 2. Transmitting light; clear; transparent. "From the brightest wines He 'd turn abhorrent." (Thomson) 3. Having qualities that render conspicuous or attractive, or that affect the mind as light does the eye; resplendent with charms; as, bright beauty. "Bright as an angel new-dropped from the sky." (Parnell) 4. Having a clear, quick intellect; intelligent. 5. Sparkling with wit; lively; vivacious; shedding cheerfulness and joy around; cheerful; cheery. "Be bright and jovial among your guests." (Shak) 6. Illustrious; glorious. "In the brightest annals of a female reign." (Cotton) 7. Manifest to the mind, as light is to the eyes; clear; evident; plain. "That he may with more ease, with brighter evidence, and with surer success, draw the bearner on." (I. Watts) 8. Of brilliant colour; of lively hue or appearance. "Here the bright crocus and blue violet grew." (Pope) Bright is used in composition in the sense of brilliant, clear, sunny, etc.; as, bright-eyed, bright-haired, bright-hued. Synonym: Shining, splending, luminous, lustrous, brilliant, resplendent, effulgent, refulgent, radiant, sparkling, glittering, lucid, beamy, clear, transparent, illustrious, witty, clear, vivacious, sunny.

| Bright, Richard | <person> English internist and pathologist, 1789-1858. See: Bright's disease. (05 Mar 2000) |
| bright's disease | <medicine> An affection of the kidneys, usually inflammatory in character, and distinguished by the occurrence of albumin and renal casts in the urine. Several varieties of Bright's disease are now recognised, differing in the part of the kidney involved, and in the intensity and course of the morbid process. Origin: From Dr. Bright of London, who first described it. Source: Websters Dictionary (01 Mar 1998) |
| bright t1 lesion | <radiology> (short T1), fat (lipoma, dermoid), sub-acute haemorrhage (metHb), paramagnetic agent (Gd, ? posterior pituitary), proteinaceous fluid (colloid cyst) most abnormalities cause long T1 and T2 (dark/bright) see also: dark T2 lesion (12 Dec 1998) |
| annular illumination | <microscopy> The result of placing a stop in the first focal plane of the condenser to produce an illuminating cone of light with all the light flux near the surface of the cone. The central part of the cone will be dark. This arrangement is often used for a darkfield effect in low-power work by transmitted light. The condenser must be correctly focused and centreed. By reflected light, darkfield illumination is attained with an annular con-denser fitted around the objective for opaque objects. Annular illumination implies that the object is lighted from all sides. (05 Aug 1998) |
| vertical illumination | <microscopy> Bright field illumination by light from the objective which is reflected or scattered from the (usually opaque) object. Illumination is by means of a vertical illuminator placed above the objective. Light is brought into a side tube and directed toward the back aperture of the objective by a tiny mirror or prism, or else by a full-aperture transparent-reflector (thin glass plate) 45[macron] to the axis of the bodytube. (05 Aug 1998) |
| central illumination | axial illumination |
| contact illumination | Illumination of the eye by means of an instrument in contact with the cornea or bulbar conjunctiva. Critical illumination, the precise focusing of the light source directly upon the object being examined. Dark-field illumination, a procedure in which a black circular shield is used to block the majority of the vertically directed rays of light (e.g., the field is dark), and a circumferential, suitably angled, mirrored surface is used to direct the peripheral rays horizontally against the object, thereby reflecting the light vertically through the objective lens and along the optical axis; thus, the object is well illuminated in a contrasting dark background. Synonym: dark-ground illumination. (05 Mar 2000) |
| dark-ground illumination | dark-field illumination |
| direct illumination | An illumination in which the rays of light are directed downward, almost perpendicularly onto the upper surface of the object, which reflects the rays upward into the optical system. Synonym: erect illumination, vertical illumination. (05 Mar 2000) |
| illumination | 1. The act of illuminating, or supplying with light; the state of being illuminated. 2. Festive decoration of houses or buildings with lights. 3. Adornment of books and manuscripts with coloured illustrations. See Illuminate. 4. That which is illuminated, as a house; also, an ornamented book or manuscript. 5. That which illuminates or gives light; brightness; splendor; especially, intellectual light or knowledge. "The illumination which a bright genius giveth to his work." (Felton) 6. The special communication of knowledge to the mind by God; inspiration. "Hymns and psalms . . . Are framed by meditation beforehand, or by prophetical illumination are inspired." (Hooker) Origin: L. Illuminatio: cf. F. Illumination. Source: Websters Dictionary (01 Mar 1998) |
| illumination, critical | <microscopy> The formation of an image of the light source in the object field. The Nelsonian method in which the light source is imaged in the plane of the specimen. A ribbon filament or arc lamp is required to give uniform illumination, the lamp must be focusable, the filament position must be adjustable in all directions. The use of an achromatic condenser is advised. Synonym: Nelson illumination. (13 Jan 1998) |
