|---|---|---|---|
| 설명 | 파장이 가시광선보다 길며 극초단파보다 짧은 750μm~1mm의 전자파. 눈으로는 볼 수 없고 일반적으로 공기 가운데에서 산란되기 어려우며, 가시광선보다 투과력이 강하다. 사진 적외선-근적외선-원적외선 따위로 나눌 수 있는데, 단파장 부분에는 사진 작용-형광 작용-광전 작용이 있어, 적외선 사진이나 적외선 통신-물질 감정-의료 따위에 이용한다. 1800년에 허셀이 발견되었다. 적외선은 물질에 부딛치며 구성분자의 열운동을 일으켜서 열효과를 주게되므로 열선이라고도 불린다. 태양광선의 약 52%는 적외선이다. 700~800nm의 적외선은 인체피부를 투과해서 피하에까지 이른다. 과도의 적외선 조사는 피부에 온열성홍반을 일으키게 해서 화상을 일으킬 수 있다. |

| spectroscopy, near-infrared | A noninvasive technique that uses the differential absorption properties of haemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional haemodynamics and blood flow. Near-infrared light (nir) can propagate through tissues and at particular wavelengths is differentially absorbed by oxgenated vs. Deoxygenated forms of haemoglobin and myoglobin. Illumination of intact tissue with nir allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.

| spectrophotometry, infrared | Spectrophotometry in the infrared region, usually for the purpose of chemical analysis through measurement of absorption spectra associated with rotational and vibrational energy levels of molecules. (12 Dec 1998) |
| spectroscopy, fourier transform infrared | A spectroscopic technique in which a range of wavelengths is presented simultaneously with an interferometer and the spectrum is mathematically derived from the pattern thus obtained. (12 Dec 1998) |
| infrared | That portion of the electromagnetic spectrum with wavelengths between 770 and 1000 nm. (05 Mar 2000) |
| infrared cataract | A cataract secondary to absorption of heat by the lens, or by transmission from the adjacent iris. Synonym: furnacemen's cataract, glassworker's cataract. (05 Mar 2000) |

| infrared rays | That portion of the electromagnetic spectrum usually sensed as heat. Infrared wavelengths are longer than those of visible light, extending into the microwave frequencies. They are used therapeutically as heat, and also to warm food in restaurants. (12 Dec 1998) |
| infrared spectroscopy | The study of the specific absorption in the infrared region of the electromagnetic spectrum; used in the study of the chemical bonds within molecules. (05 Mar 2000) |
| infrared spectrum | The part of the invisible spectrum of wave length just longer than that of visible red light. Synonym: thermal spectrum. (05 Mar 2000) |
| pupillary light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| near | 1. Not far distant in time, place, or degree; not remote; close at hand; adjacent; neighboring; nigh. "As one near death." "He served great Hector, and was ever near, Not with his trumpet only, but his spear." (Dryden) 2. Closely connected or related. "She is thy father's near kinswoman." (Lev. Xviii. 12) 3. Close to one's interests, affection, etc.; touching, or affecting intimately; intimate; dear; as, a near friend. 4. Close to anything followed or imitated; not free, loose, or rambling; as, a version near to the original. 5. So as barely to avoid or pass injury or loss; close; narrow; as, a near escape. 6. Next to the driver, when he is on foot; in the Unted States, on the left of an animal or a team; as, the near ox; the near leg. See Off side, under Off, . 7. Immediate; direct; close; short. "The nearest way." 8. Close-fisted; parsimonious. Near may properly be followed by to before the thing approached'; but more frequently to is omitted, and the adjective or the adverb is regarded as a preposition. The same is also true of the word nigh. Synonym: Nigh, close, adjacent, proximate, contiguous, present, ready, intimate, dear. Origin: See Near. Source: Websters Dictionary (01 Mar 1998) |
| near drowning | Any almost drowning. All cases should be evaluated by a physician. Complications include aspiration pneumonia and adult respiratory distress syndrome. (27 Sep 1997) |
| near infrared |
short-wave infrared, infrared radiation of the shortest wavelength, ie, closest to the visible spectrum (wavelength about 0.75 to 3.0 mm).

| near infrared |
The region of the electromagnetic spectrum between 0.77 to 1.4 microns. Most of the infrared solar radiation falls into this region. This near infrared (or solar IR) region is transmitted, absorbed, and reflected in a similar manner to visible light by most glazing and nonmetallic building materials.

| near infrared |
Near Infrared light is not visible to human eyes, but many celestial objects shine brightly with this light. Typically associated with heat, NIR images show the presence of molecules and complex compounds.
