| 설명 | 외부로부터 들어온 자극을 잘못 판단하는 것을 착각이라고 한다. 외부에서 들어온 자극을 받아들이는 말초감각기관은 정확히 자극을 받아 들였지만 이것을 해석하는 뇌의 작용의 이상으로 그 자극을 과소, 과대평가하거나 다른 것으로 생각하는 것이다. 예를 들면 멀리서 걸어오는 처음 보는 여자를 자신의 애인으로 잘못보는 것이 착각이다. 이런 현상은 독성물질에 의한 뇌실질의 장애, 뇌의 감염, 알코올성 정신병, 뇌의 변성 등 뇌 자체의 병으로 인한 혼돈된 상태나 다른 전신의 장애, 즉 고열, 심한 전신쇠약 등에서 생기는 혼돈상태에서 나타날 수가 있다. 그리고 정상적인 상태에서도 볼 수 있다. |

| illusion | 1. <psychology> An unreal image presented to the bodily or mental vision; a deceptive appearance; a false show; mockery; hallucination. "To cheat the eye with blear illusions." (Milton) 2. Hence: Anything agreeably fascinating and charning; enchantment; witchery; glamour. "Ye soft illusions, dear deceits, arise!" (Pope) 3. <physiology> A sensation originated by some external object, but so modified as in any way to lead to an erroneous perception; as when the rolling of a wagon is mistaken for thunder. Some modern writers distinguish between an illusion and hallucination, regarding the former as originating with some external object, and the latter as having no objective occasion whatever. Illusion refers particularly to errors of the sense, delusion to false hopes or deceptions of the mind. An optical deception is an illusion, a false opinion is a delusion. Synonym: Delusion, mockery, deception, chimera, fallacy. Origin: F. Illusion, L. Illusio, fr. Illudere, illusum, to illude. Source: Websters Dictionary (01 Mar 1998) |

| illusion of doubles | <syndrome> The delusional belief that a person (or persons) close to the schizophrenic patient has been substituted for by one or more impostors; may have an organic aetiology. Synonym: Capgras' phenomenon, illusion of doubles. (05 Mar 2000) |
| illusion of movement | Successive stimulation of neighboring retinal points which causes the sensation of movement. Oculogravic illusion, apparent movement of the visual field when the body is subjected to acceleration; due to gravity. Oculogyral illusion, an illusion occurring in angular acceleration in which the position of fixed light appears to drift. Optical illusion, a false interpretation of the colour, form, size, or movement of a visual sensation. (05 Mar 2000) |
| axis, optical | <microscopy> Usually refers to the axis on which several principal lens axes may lie. It also refers to the axis of the eye which extends through the centre of the eye lens. The line formed by the coinciding principal axes of a series of optical elements comprising an optical system. It is the line passing through the centres of curvature of the optical surfaces. (05 Aug 1998) |
| specific optical dispersion | <microscopy> The difference between the refractive indices of light of two different wavelengths, both indices measured at the same temperature, the difference being divided by the specific gravity also measured in the same medium at the test temperature. For convenience, the specific dispersion value is multiplied by ten. (05 Aug 1998) |
| optical | 1. Of or pertaining to vision or sight. "The moon, whose orb Through optic glass the Tuscan artist views." (Milton) 2. Of or pertaining to the eye; ocular; as, the optic nerves (the first pair of cranial nerves) which are distributed to the retina. 3. Relating to the science of optics; as, optical works. <optics> Optic angle, a graduated circle used for the measurement of angles in optical experiments. Optical square, a surveyor's instrument with reflectors for laying off right angles. Origin: F. Optique, Gr.; akin to sight, I have seen, I shall see, and to the two eyes, face, L. Oculus eye. See Ocular, Eye, and cf. Canopy, Ophthalmia. Source: Websters Dictionary (01 Mar 1998) |
| optical aberration | Failure of rays from a point source to form a perfect image after traversing an optical system. (05 Mar 2000) |
| optical activity | The ability of a material to rotate the plane of polarized light. (09 Oct 1997) |
| optical antipode | <chemistry> A pair of chiral isomers (stereoisomers) that are direct, nonsuperimposable mirror images of each other. (09 Jan 1998) |
| optical axis | <physics> The line passing through both the centres of curvature of the optical surfaces of a lens, the optical centreline for all the centres of a lens system. (09 Oct 1997) |
| optical density | 1. <chemistry, investigation> Absorbance is defined as a logarithmic function of the percent transmission of a wavelength of light through a liquid. 2. <microbiology> This can be used as a measure of the amount of light absorbed by a suspension of bacterial cells or a solution of an organic molecule, it is measured by a colourimeter or spectrophotometer. Absorbance values are used to plot the growth of bacteria in suspension cultures and to gauge the purity and concentration of molecules (such as proteins) in solution. See: absorption. (15 Jan 1998) |
| optical diffraction | A technique used to obtain information about repeating patterns. Diffraction of visible light can be used to calculate spacings in the object. (18 Nov 1997) |
| optical flat | <microscopy> Usually, a glass or quartz plate or disk, the thickness of which should be at least 1/10 of its diameter. It is ground until any remaining unevenness can be measured only by interferometric methods. Their maximum departure from flatness usually is less than 1/10 of the sodium doublet (589.3 nm). (05 Aug 1998) |
| optical image | An image formed by the refraction or reflection of light. (05 Mar 2000) |
| optical index | <microscopy> A constant applied to objectives for purposes of comparison. It takes into account the focal length or magnifying power of the lens and also the numerical aperture. It was offered by Nelson and by Coles, but little use has been made of the optical index figure, probably because the equations of the two men differed and the resulting figures have been at variance.
