aberrations

listen to the pronunciation of aberrations
Englisch - Englisch
a deviation in power of the optical components of the eye, (either individually or in combination), from the ideal system that would produce a perfect point image on the retina The aberrations induced by refractive surgery are best described as irregular but some studies tend to refer to them as being most similar to spherical aberration and coma
A phenomenon in optics that cause the reproduction of a point as a patch or a straight line as a more or less curved band, and chromatic errors There are six types of aberrations -- Seidel's five aberrations (spherical aberration, coma, astigmatism, curvature of field and distortion) and chromatic aberration
plural of aberration
Effects associated with the performance of optical components which give rise to imperfect optical images
Distortions in the wavefront which result in a blurry image
Imperfections, irregularities and/or distortions of the optical quality of the eye
Causes completely blurred images There are six types of aberrations: spherical, coma, astigmatism, curvature of field, distortion and chromatic

aberration
A mental disorder, especially one of a minor or temporary character
aberration
Any optical defect and/or design error which causes any of the processed light to deviate from reaching the focal point, therefore reducing the quality of the image Field of View: The maximum view angle of an optical instrument The number, in degrees, supplied by the manufacturer is the Apparent Field of View To find the Actual Field of View ( also known as the Actual Field of View ), divide the Apparent Field of View by the Magnification

aberration
Deviation from the straight line Responding, thinking, feeling, or acting in ways that aren't really aligned with what one wants
aberration
a departure from rational thought or behavior From the Latin, aberrare, to wander from; Latin, ab, away, errare, to wander It means basically to err, to make mistakes, or more specifically to have fixed ideas which are not true The word is also used in its scientific sense It means departure from a straight line If a line should go from A to B, then if it is aberrated it would go from A to some other point, to some other point, to some other point, to some other point, to some other point, and finally arrive at B Taken in its scientific sense, it would also mean the lack of straightness or to see crookedly as, in example, a man sees a horse but thinks he sees an elephant Aberrated conduct would be wrong conduct, or conduct not supported by reason Aberration is opposed to sanity, which would be its opposite
aberration
a disorder in one's mental state
aberration
A defect of an optical image caused by the fact that essentially no lens system can form a perfect image
aberration
Property of an optical system that causes an image to have certain easily recognizable flaws Aberrations are caused by geometrical factors such as the shapes of surfaces, their spacing, and alignments Image problems caused by factors such as scratches or contamination are not called aberrations
aberration
This is the inability of the camera lens to produce a true image There is no such thing as a ‘perfect lens’, generally the more expensive the lens the less aberrations there are in the picture quality
aberration
Scientology A departure from rational thought or behavior From the Latin, aberrare, to wander from; Latin, ab, away, errare, to wander It means basically to err, to make mistakes, or more specifically to have fixed ideas which are not true The word is also used in its scientific sense It means departure from a straight line If a line should go from A to B, then if it is aberrated it would go from A to some other point, to some other point, to some other point, to some other point, to some other point, and finally arrive at B Taken in its scientific sense, it would also mean the lack of straightness or to see crookedly as, in example, a man sees a horse but thinks he sees an elephant Aberrated conduct would be wrong conduct, or conduct not supported by reason Aberration is opposed to sanity, which would be its opposite
aberration
A small periodical change of position in the stars and other heavenly bodies, due to the combined effect of the motion of light and the motion of the observer; called annual aberration, when the observer's motion is that of the earth in its orbit, and daily or diurnal aberration, when of the earth on its axis; amounting when greatest, in the former case, to 20
aberration
Planetary aberration is that due to the motion of light and the motion of the planet relative to the earth
aberration
1 In an imaging system, the failure to obtain a simple point-to-point correspondence between the astronomical object and the image, as in, e g chromatic aberration, spherical aberration 2 In astrometry, the angular displacement of the apparent direction to an astronomical object resulting from the Earth's orbital motion with velocity v and the finite velocity of light c For earth-based observers, an object annually describes an ellipse on the celestial sphere whose semi-major axis is arctan(v/c), i e 20 496"; the eccentricity of the ellipse is zero for an object at the ecliptic pole, and the ellipse degenerates to a straight line for an object in the ecliptic plane
aberration
A partial alienation of reason
aberration
a flaw in a mirror or lens causing rays of light from a single point to fail to focus at a single spot in space
aberration
an optical phenomenon resulting from the failure of a lens or mirror to produce a good image
aberration

aberration

aberration

aberration
3''
aberration

aberration

aberration

aberration
An optical defect in a lens causing it to form an image that is not sharp or one that is distorted
aberration
An aberration is an incident or way of behaving that is not typical. It became very clear that the incident was not just an aberration, it was not just a single incident. an action or event that is different from what usually happens or what someone usually does. Deviation of light rays by lenses or mirrors which causes the images to be blurred. Spherical aberration occurs because curvature in a lens or mirror causes rays falling on the outer edges to be brought to a focus at a different point from those from the middle. This makes the images formed appear blurred. Chromatic aberration, which occurs in lenses but not mirrors, is the failure of a lens to focus all colours (wavelengths) of light in the same plane; the image appears blurred and shows rainbow-coloured fringes around the edges. See also astigmatism
aberration
The passage of blood or other fluid into parts not appropriate for it
aberration
(1) a disturbance in color that interfere with clarity, typically one of the faults found in interpolated colors; (2) errors in a photographic lens which prevent the lens from producing a single focus of all intensities of the light rays reflected from the subject, resulting in poor image definition at the film plane
aberration
An optical defect in a lens causing the lens to form an image that is not sharp or that is distorted
aberration
The convergence to different foci, by a lens or mirror, of rays of light emanating from one and the same point, or the deviation of such rays from a single focus; called spherical aberration, when due to the spherical form of the lens or mirror, such form giving different foci for central and marginal rays; and chromatic aberration, when due to different refrangibilities of the colored rays of the spectrum, those of each color having a distinct focus
aberration
Any errors that result in image degradation Such errors may be chromatic, spherical, astigmatic, or comatic, and can result from design or execution, or both In an optical system, the aberration of light refers to the straying away of rays from their appointed courses These errors, unless corrected, tend to produce a hazy image and give rise to spherical aberration, coma, astigmatism, curvature of field, distortion, and longitudinal and lateral chromatic error Aberration, Chromatic Present in a lens system when the rays of the component colours of white light are not brought to one focus, thus producing colour fringes in the image
aberration
{i} deviation, irregularity, abnormality
