|---|---|---|---|
| 설명 | 물체의 미세한 부분을 확대하여 관찰하는 장치. 대개의 경우는 대물렌즈와 접안렌즈를 갖추고 있는 현미경을 말하나, 넓은 뜻으로는 전자선을 이용하는 전자현미경을 포함하며, 확대경도 단일 렌즈계를 갖는 단현미경이라 할 수 있다. 종류와 형은 사용목적-제작연대-제작 회사의 차이에 따라 여러 가지가 있으나 구조적으로 분류하면, 가장 일반적인 투과현미경 이외에 금속현미경-편광현미경-형광현미경-위상차현미경-자외선현미경 등의 특수한 것들이 있다. 현미경이 물체의 상을 확대하는 원리는 초점거리가 짧은 대물렌즈에 의하여 얻어지는 확대된 도립실상을 접안렌즈로 다시 확대하는 것이다. 이 결상관계는 대단히 예민하여 물체와 대물렌즈 사이의 거리가 조금만 변하여도 바른 상을 맺지 못한다. |

| interference microscope | <instrument> A specially constructed microscope in which the entering light is split into two beams which pass through the specimen and are recombined in the image plane where the interference effects make the transparent (invisible) refractile object details become visible as intensity differences; permits measurements of light retardation, index of refraction, and thickness and mass of specimen; it is useful in the examination of living or unstained cells.

| bacterial interference | The condition in which colonization by one bacterial strain prevents colonization by another strain. (05 Mar 2000) |
|---|---|
| viral interference | A phenomenon in which infection by a first virus results in resistance of cells or tissues to infection by a second, unrelated virus. (12 Dec 1998) |
| microscopy, interference | Microscopy in which physiological and photometric contrast in the image is influenced or produced by the action of optical components which regulate interference. (12 Dec 1998) |
| cuspal interference | A condition of tooth contact's which diverts the mandible from a normal path of closure to centric jaw relation. Synonym: cuspal interference, interceptive occlusal contact, premature contact. (05 Mar 2000) |
| Newton's interference colours | <microscopy> Newton's series of colours by interference results when two wave-trains of white light meet. For some wavelengths (colours) there will be destructive interference (darkness) but for other wavelengths there will be reinforcement (colour). They are most frequently observed in very thin films, only wavelengths thick, for example, oil on water. The interference is caused by partially reflected light from the interfaces. Newton's series of colours appears in sequence in the Michel-Levy chart. (05 Aug 1998) |
| differential interference contrast | <technique> A mode of contrast generation in microscopy that yields an image with a shadow relief. The relief reflects the gradient of optical path difference. Differential Interference Contrast, which is a form of interferenc microscopy that uses polarizing beam splitters, can be of the Smith or Nomarski type. Acronym: DIC (05 Aug 1998) |
| dissociation by interference | The simultaneous operation of two separate cardiac pacemaking foci that are unassociated because of interference (a normal physiologic phenomenon) due to rendering their respective territories refractory to each other. Usually atrioventricular dissociation is indicated, the rates being quite close to each other with the atrial rate slightly faster than that of the pacemaker in control of the ventricles. Capture is in either direction, usually the ventricle by the atrium, in incomplete dissociation. H Synonym: dissociation by interference. (05 Mar 2000) |
| interference | Opposition or hampering of an action or procedure. Origin: L. Ferire = to strike (18 Nov 1997) |
| interference beat | Ventricular capture in forms of A-V dissociation due to interference. (05 Mar 2000) |
| interference colours | <microscopy> Michel-Levy colour chart of birefringence/retardation vs. Thickness. (05 Aug 1998) |
| interference diffraction patterns | The patterns arising from the recombination of beams of light or other waves after they have been split and one set of rays have undergone a phase retardation relative to the other. Such patterns formed by simple objects give information on the correctness of the focus and the presence or absence of optical defects. (18 Nov 1997) |
| interference dissociation | The simultaneous operation of two separate cardiac pacemaking foci that are unassociated because of interference (a normal physiologic phenomenon) due to rendering their respective territories refractory to each other. Usually atrioventricular dissociation is indicated, the rates being quite close to each other with the atrial rate slightly faster than that of the pacemaker in control of the ventricles. Capture is in either direction, usually the ventricle by the atrium, in incomplete dissociation. H Synonym: dissociation by interference. (05 Mar 2000) |
| interference figure | <microscopy> The conoscopic pattern of extinction positions of a crystal superimposed on the pattern of interference colours corresponding to the full cone of directions by which the crystal is illuminated, each direction showing its own interference colour. (05 Aug 1998) |
| interference microscopy | <procedure> Although all image formation depends on interference, the term is generally restricted to systems in which contrast comes from the recombination of a reference beam with light that has been retarded by passing through the object. Because the phase retardation is a consequence of the difference in refractive index between specimen and medium and because the the refractive increment is almost the same for all biological molecules, it is possible to measure the amount of dry mass per unit area of the specimen by measuring the phase retardation. Quantification of the phase retardation is usually done by using a compensator to reduce the bright object to darkness (see Senarmont and Ehrlinghaus compensators). Two major optical systems have been used the Jamin Lebedeff system and the Mach Zehnder system. These instruments are often referred to as interferometers, since they are designed for measuring phase retardation. Although their use has passed out of fashion, it may be that they will be employed more frequently in future in conjunction with image analysing systems. (18 Nov 1997) |
| interference reflection microscopy | <procedure> An optical technique for detecting the topography of the side of a cell in contact with a planar substrate and for providing information on the separation of the plasmalemma from the substrate. Interference between the reflections from the substrate medium interface and the reflections from the plasmalemma medium interface generate the image. (18 Nov 1997) |
